  • Nginx infinite redirect loop

    - by Zachary Burt
    Why is http://compassionpit.com/blog/ going through an infinite redirect loop? Here's my nginx conf file. The site is run by a nodejs server on port 8000 and Apache serves up the blog (wordpress) and the forum (phpBB). The forum is resolving just fine, at http://www.compassionpit.com/forum/ ... server { listen 80; server_name www.compassionpit.org; rewrite ^/(.*) http://www.compassionpit.com/$1 permanent; } server { listen 80; # your server's public IP address server_name www.compassionpit.com; index index.php index.html; location ~ ^/$ { proxy_pass http://127.0.0.1:8000; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location @blogphp { internal; root /opt/blog/; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root/index.php; fastcgi_index index.php; fastcgi_pass 127.0.0.1:8080; } location ~ ^/(forum|blog)/($|.*\.php) { root /opt/; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_index index.php; fastcgi_pass 127.0.0.1:8080; } location ~ ^/(forum|blog) { root /opt/; try_files $uri $uri/ @blogphp; } location ~ ^/(forum|blog)/ { root /opt/; } location @backend { internal; proxy_pass http://127.0.0.1:8000; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } location ~ / { root /opt/chat/static/; try_files $uri $uri/ @backend; } }

  • Dynamic subdomain routing

    - by Nader
    Hi everyone, I asked this question over at stackoverflow, but got very few views: http://stackoverflow.com/questions/2284917/route-web-requests-to-different-servers-based-on-subdomain Perhaps it's more applicable to this crowd. Here it is again for convenience: I have a platform where a user can create a new website using a subdomain. There will be thousands of these, eg abc.mydomain.com, def.mydomain.com . Hopefully if we are successful hundreds of thousands. I need to be able to route these domains to a different IPs to point at a particular app server. I have this mapping in a database right now. What are the best practices and recommended technologies here? I see a couple options: Have DNS setup with a wildcard CNAME entry so that all requests go to a single IP where perhaps two machines using heartbeat (for failover) know how to look up the IP in the database and then do an http redirect to the appropriate app server. This seems clunky and slow to me. Run my own DNS server that can be programatically managed such that when a new site is created a DNS entry is added. We also move sites around to different app servers, so I would need to be able to update DNS entries in close to real time. Thoughts anyone? Thanks. Update2: I've setup external wildcard DNS pointing at an HAProxy web server whose job it is to route requests to backend servers. The mapping is stored in our internal PowerDNS server. Question now is how to get the HAProxy server (or another) to use the value of the internal DNS and not some config file or access list? – Update: Based on some suggestions below, it seems like reverse-proxy server(s) is the way to go. As I'll be rebalancing the domain-server mapping, these need to work instantly and the TTL on a DNS solution could be a problem. Any recommendations on software to use considering this domain-IP data is stored in a DB, and I'll need this to be performant?

  • certificate working on IP but not on URL

    - by Stephan
    I asked this question on stackoverflow, and I've been suggested to repost it here. I have a problem accessing my site (on https) with IEMobile 9 (WP 7.5). It says it's got problem with the certificate, as if it wasn't valid. Everything works on any other browser or platform I tested (android (several phones and a galaxy tab with stock browser, firefox, opera, dolphin), iOS (iphone and ipad with safari and chrome), an old nokia with symbian, windows 7, linux and mac). To try to solve this I saved the certificate (.cer) on the server and accessed it from the phone browser. It always complained except when I accessed it through the server IP (192.168.xx.xx). At that point it (said it) installed correctly the certificate. If then I try to access the index.html still using the IP all works fine and it doesn't complain about the certificate. If, though, I try to access the index using the actual URL (blah.myblah.com), it complains again about the certificate, as if it wasn't installed! It isn't a problem of DNS, cause that's up and serving the right ip, and the phone is correctly setup to use it. The certificate is signed by geotrust/rapidssl for *.myblah.com.

  • download management

    - by Jonathan
    I download many files, usually 2 or 3 a day, often 10ish. Some of them are duplicates because I just can't be bothered to find the original in my downloads folder. I have previously tried DAP and used that to create a new subfolder for each day's download. yet I have found this insufficient as sometimes I wish to find files by name/file type or I have multiple parts of downloads over more than one day. Another problem I have found is zips/rars/etc after downloading them and extracting them I then have the zip and the folder. I like it like on a Mac where it automatically extracts the zip after it has been downloaded and removes the zip. What I'd like to be able to do is sort the downloads by date, but dynamically so they are just in the big downloads folder, but I can just press a button and it will show me all the files from a particular site, or from a particular day or by a certain file type. Is there any software that will do this? I use Chrome as a browser but also have Firefox and like that. Jonathan

  • installing Conkeror on Ubuntu 12.04

    I am reading the instructions on conkeror site (and elsewhere) on how to install conkeror on Ubuntu (I am using Ubuntu 12_04 LTS) and it seems that the correct sequence is: sudo apt-add-repository ppa:xtaran/conkeror sudo apt-get update sudo apt-get install conkeror conkeror-spawn-process-helper The first step (apt-add-repository) seems to execute without a problem, giving the following output: You are about to add the following PPA to your system: Conkeror Debian packages for Ubuntu releases without xulrunner (i.e. for 11.04 Natty and later) More info: https://launchpad.net/~xtaran/+archive/conkeror Press [ENTER] to continue or ctrl-c to cancel adding it Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret- keyring /tmp/tmp.Re7pWaDEQF --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp://keyserver.ubuntu.com:80/ --recv CB29CBE050EB1F371BAB6FE83BE0F86A6D689050 gpg: requesting key 6D689050 from hkp server keyserver.ubuntu.com gpg: key 6D689050: "Launchpad PPA for Axel Beckert" not changed gpg: Total number processed: 1 gpg: unchanged: 1 However, the apt-get update seems unable to fetch packages from the newly added PPA, with its output ending in: Hit http://security.ubuntu.com precise-security/restricted Translation-en Hit http://security.ubuntu.com precise-security/universe Translation-en Err http://ppa.launchpad.net precise/main Sources 404 Not Found Ign http://extras.ubuntu.com precise/main Translation-en_US Err http://ppa.launchpad.net precise/main i386 Packages 404 Not Found Ign http://extras.ubuntu.com precise/main Translation-en Ign http://ppa.launchpad.net precise/main Translation-en_US Ign http://ppa.launchpad.net precise/main Translation-en W: Failed to fetch http://ppa.launchpad.net/xtaran/conkeror/ubuntu/dists/precise /main/source/Sources 404 Not Found W: Failed to fetch http://ppa.launchpad.net/xtaran/conkeror/ubuntu/dists/precise/main/binary-i386/Packages 404 Not Found E: Some index files failed to download.

  • How do I disable the firewall on blackberry?

    - by user15660
    I own a Blackberry 9630 tour.(Sprint). The firewall is enabled with a lock sign and grayed out. I'm not able to disable it. Because of this many of my blackberry apps don't work as it gives a message "The application has tried to open a connection that's not allowed by your IT policy". I tried all options and there's nothing to disable. This is a personal blackberry and I don't have an IT policy on it. I did all methods like wiping, formatting/resetting to factory settings acc. to blackberry site by running their reset app from PC etc etc. but nothing works I tried CrackUtil for blackberry and that worked and wiped the blackberry. I restored my bb and started using it just to notice that the firewall is enabled back after a desktop manager connection to PC. I even made sure the policy.bin file on PC is a regular one with no IT policy. How do I get this disabled? I had the same problem on my old blackberry 8330 and crackutil disabled the firewall. but after a few days after a desktop manager update of blackberry OS and other small stuff the firewall got enabled again. Please give me a solutions to disable the firewall on blackberry

  • How do i set up a fully featured small business network?

    - by JoshReedSchramm
    This has the possibility to be a very large question but I recently acquired a few rack mount servers and the hardware necessary to run them. Unfortunately I'm a programmer with very little understanding of how to set up a good working network so I'm hoping someone on here might be able to help. What I want to do is run a domain with a series of subdomains which would all be externally accessible. The setup would live inside my home and my internet connection is your run of the mill cable model (which means a dynamic IP) I want to be able to set up a couple site, specifically: www.mycompany.com (mycompany.com with no subdomain would redirect to this) build.mycompany.com (for my continuous integration server) ruby.mycompany.com (for ruby projects) win.mycompany.com (for windows project) etc. Additionally this is still my home network so our personal machines need to be able to get on via wifi with at least the same security we have now through an out of the box router from best buy. I'm thinking i need a DNS server, DHCP server and one of those would run either no-ip or dyndns to accommodate the dynamic ip. I don't necessarily need mail but it might be helpful to have some sort of mail server i could use for testing, it doesn't need to get out to the greater internet though. So how do i set up this kinda of network? tl;dr Need to know how to set up your standard office style network in my home off my normal consumer level cable modem connection.

  • How can Django/WSGI and PHP share / on Apache?

    - by Mark Snidovich
    I have a server running an established PHP site, as well as some Django apps. Currently, a VirtualHost set up for PHP listens on port 80, and requests to certain directories are proxied to a VirtualHost set up for Django with WSGI. I'd like to change it so Django handles anything not existing as a PHP script or static file. For example, / -parsed by PHP as index.php /page.php -parsed as PHP normally /images/border.jpg -served as a static file /johnfreep -handled by Django (interpreted by urls.py) /pages/john -handled by Django /(anything else) - handled by Django I have a few ideas. It seems the options are 'php first' or 'wsgi first'. set up Django on port 80, and set Apache to skip all the known PHP, CSS or image files. Maybe using SetHandler? Anything else goes to Django to be parsed by urls.py. Set up a script referring everything to Django as a 404 handler on PHP. So, if a file is not found for a name, it sends the request path to a VirtualHost running Django to be parsed.

  • Looking for suitable backup solution Mac OS X to offsite Centos 6 server 1TB of working data

    - by Brady
    I'll start by saying what we have in place currently: On site file server (Mac OS X Server) that is used by GFX designers and they have a working 1TB of data. Offsite server with 2TB available storage (Centos 6) Mac OS X server rsync data to offsite server every 6 hours (rsync -avz --delete --progress -e ssh ...) Mac OS X server does full data backup to LTO 4 tape on a 10 day recycle (Mon-Fri for 2 weeks) rsync pushes about 60GB of file changes a day. The problem: The onsite tape backup is failing as 1TB of graphics files don't compress well to fit onto a 800GB LTO4 tape. Backup is incredibly slow doing a full backup. Pain in the backside getting people to remember to change the tape. Often gets forgotten etc The quick solution: Buy LTO5 Drive and tapes. However this has been turned down because of the cost... What I would like: Something that works in the same way rysnc works. Only changed data is sent over the wire and can be scheduled to run multiple times during the day. Data that is sent is compressed and sent over SSH. Something that keeps a 14day retention but doesn't keep duplicate data So as an example if I have 1TB of working data and 60GB of changes are made each day then I expect around 1.84TB of data to be stored on the offsite server. To work with the Mac OS X server and Centos 6 server. Not cost an arm and a leg. Must be a cheaper solution than buying an LTO5 drive with tapes (around £1500). Be able to be setup to run autonomously. Have some sort of control panel that will allow an admin to easily restore a file/folder. Any recommendations?

  • Free tiered storage automation in linux?

    - by NginUS
    I have a couple virtualized fileservers running in QEMU/KVM on ProxmoxVE. The physical host has 4 storage tiers with significant performance variances. They're attached both locally and via NFS. These will be provided to the fileserver(s) as local disks, abstracted into pools, and handling multiple streams of data for the network. My aim is for this abstraction layer to intelligently pool the tiers. There's a similar post on the site here: Home-brew automatic tiered storage solutions with Linux? (Memory - SSD - HDD - remote storage) in which the accepted answer was a suggestion to abandon a linux solution for NexentaStor. I like the idea of running NexentaStor. It almost fits the bill. NexentaStor provides Hybrid Storage Pools, and I love the idea of checksumming. 16TB without incurring licensing fees is a huge plus as well. After the expense of the hardware, free is about all my budget can handle. I don't know if zfs pools are adaptive or dynamically allocated based on load, but it becomes irrelevant since NexentaStor doesn't support virtio network or block drivers, which is a must in my environment. Then I saw a commercial solution called SmartMove: http://www.enigmadata.com/smartmove.html And it looks like a step in the right direction, but I'm so broke I'd be wasting their time to even ask for a quote, so I'm looking for another option. I'm after a linux implementation that supports virtio drivers, and I'm at a loss as to which software is up to it.

  • Starting my own server - basic recommendations and questions [closed]

    - by Ilia Rostovtsev
    Possible Duplicate: Can you help me with my capacity planning? I'm planning to start my own high-performance server and then use collocation services for keeping it up and running. I'm planning to USE it for processing videos and keeping big video site up! (using FFMpeg, MENcoder and etc.) I just need recommendations on whether listed hardware is good enough and will work together well and fast enough. Do I need anything else (missed something). I remember about CPU coolers though! ;) I'm planning to use SSD drives so please tell me if it's going to work just as regular HDDs (but much faster)? Are they going to be used as RAID (is this possible for SSDs)? Here is what I would like to get: Intel ® Server System SR1600URHSR (Urbanna) or Intel® Server System SR1695WBAC 2 x Intel Xeon X5650 4 x 16Gb DDR-III 1333MHz Kingston ECC Reg (KVR13R9D4/16) 3 x (or maybe 4x) 480Gb SSD Intel 520 Series (SSDSC2CW480A3K5) Which server system would be better? Is listed hardware new/good enough and worth buying it at the moment? Should I probably take a look at something slightly more expensive but more up to date and powerful, may be? After all as software I would like to use CentOS 6 64 bit + WHM/CPanel? Any other suggestions on maybe cheaper and same/more powerful server management system but WHM? What most important points to keep in mind when starting/maintaining your own server?

  • Using GUI ftp on Win7 and Vista without additional software

    - by Stephen Jones
    Goal: provide a 'no-software' method for 'less technical' users to access password protect ftp location from Win7 and Vista (existing approach for WinXP works). 'No software' method to mean without installing additional software (e.g. FileZilla, WinSCP) - the solution is supplied to external non-technical users. WinXP (works): Using Windows Explorer, WinXP supports non-technical ftp access by pasting: ftp://username:[email protected] into the address bar. The remote ftp site's files / directory structure becomes available and can be copied to / from easily (in the style of local file copy / paste) by a 'less technical' user. Win7 / Vista (doesn't work): Pasting the same URL into the Windows Explorer on Win7 or Vista causes an error: An error occurred opening that folder on the FTP server. Make sure you have permission to access that folder. Details: The connection with the server was reset. Notes: a) The same username/password/server typed from the (DOS) command line achieves access to the server, but this is a more 'technical' solution than desired. I am looking for a WinXP equivalent solution. b) Under 'Control Panel' / 'Internet options' / 'Advanced' tab - the boxes for 'Enable FTP folder view' and 'Use Passive FTP' are ticked (enabled) c) Adding an inbound firewall rule for local port 20 (TCP) was attempted with no difference in results (i.e. failure)

  • Setup Version Control on Dreamweaver

    - by John Isaacks
    I have a win computer on the Network called WIN2K8FS1 I have TortoiseSVN on a win computer and when I go to checkout a repository with Tortoise it asks me for the URL of the repository. I put in: file://WIN2K8FS1/Media/SVN_repo And it creates the working copy. I am trying to setup Dreamweaver CS5 to work with subversion. I create a new site and I go to the Version Control tab and it asks for a lot if info. First is Access. I choose Subversion since that is the only option Second is Protocol. Not sure which I need so I go with HTTP? Third is Server Address. I am assuming this is the name of the computer with the repository so I put in \\WIN2K8FS1\ Fourth is Repository Path. I put in /Media/SVN_repo Fifth is Port which I leave default to 80 Then it asks for user name and password. I never set one up for anything so I put in my domain username and password. I click test and it tells me: Server and project are not accessible! I am not sure what I am doing wrong. I am not the server admin but I did create the repository and have access to it via Tortoise. So I am not sure what I am doing wrong in Dreamweaver.

  • Domain names timing out after VPS IP change

    - by Fourjays
    I rent a CentOS 5 VPS from a UK-based provider, with DirectAdmin also installed. On Thursday night, they carried out planned maintenance to changed the two IPs I had been assigned to two new ones. On Friday, after the change had taken place, I updated my domain name records to reflect the IP change. Since then, all of the domains pointing to the VPS are timing out. Additionally, DirectAdmin was also not responding, but was was resolved by running the ipswap scripts as found in the DirectAdmin knowledgebase. It did not fix my domains though. I have contacted the VPS provider but I have been waiting for a response for some time now. I have checked again, and again, and all the IPs referenced in DirectAdmin are correct. If I go to the server IP in my browser it responds with "Apache is functioning normally." Email accounts on the server are also functioning correctly. But if I access a domain itself, it times out. Running a ping and a DNS look-up, I can confirm the nameserver IPs are correct. If I run a trace route it reaches an IP that is similar to my VPS IPs (last 2 blocks are different) before timing out (it never shows my server IP). I am relatively new to VPS management so don't have a vast wealth of experience with troubleshooting problems on them. I have checked all of the httpd configuration files, which don't seem to have any IP references in them at all. Looking in the Apache error logs, what errors there are do not coincide with times I have tried to access the site. Is this issue at my provider's end? Is there anything else I can check or test, to rule out post-IP-change problems with my server configuration? It was all running fine prior to the IP change.

  • Scanning website for vulnerablities

    - by Kristen
    I have found that the local school's website installed a Perl Calendar - this was years ago, it has not been used for ages, but Google has it indexed (which is how I found it) and it full of Viagra links and the like ... program was by Matt Kruse, here is details of the exploit: http://www.securiteam.com/exploits/5IP040A1QI.html I've got the school to remove that, but I think they also have MySQL installed and I'm aware that out-of-the-box there have been some exploits of Admin Tools / Login in old versions. For all I know they also have PHPBB and the like installed ... The school is just using some cheap, shared hosting; the HTTP response header I get is: Apache/1.3.29 (Unix) (Red-Hat/Linux) Chili!Soft-ASP/3.6.2 mod_ssl/2.8.14 OpenSSL/0.9.6b PHP/4.4.9 FrontPage/5.0.2.2510 I'm looking for some means of checking if they have other junk installed (quite possibly from way back, and now unused) that might put the site at risk. I'm more interested in something that can scan for things like the MySQL Admin exploit rather than open ports etc. My guess is that they have little control over the hosting space that they have - but I'm a Windows DEV, so this *nix stuff is all Greek to me. I found http://www.beyondsecurity.com/ which looks like it might do what I want (within their evaluation :) ) but I have a worry about how to find out if they are well known / honest - otherwise I will be tipping them a wink with a Domain Name that may be at risk! Many thanks.

  • How to debug slow queries in Django+Postgres

    - by lacker
    My database queries from Django are starting to take 1-2 seconds and I'm having trouble figuring out why. Not too big a site, about 1-2 requests per second (that hit Django; static files are just served from nginx.) The thing that confuses me is, I can replicate the slowness in the Django shell using debug mode. But when I issue the exact same queries at an sql prompt they are fast. It takes about a second for a query to return, but when I check connection.queries it reports the time as under 10 ms. Here's an example (from the Django shell): >>> p = PlayerData.objects.get(uid="100000521952372") >>> a = time.time(); p.save(); print time.time() - a 1.96812295914 >>> for d in connection.queries: print d["time"] ... 0.002 0.000 0.000 How can I figure out where this extra time is being spent? I'm using Apache+mod_wsgi in daemon mode, but this happens with just the django shell as well, so I figure it is not apache-related.

  • Problem IIS 7.0 Locking files durring upload

    - by viscious
    I am running a server 2008 with iis7 and the ftp addon on to iis 7.0 I have the ftp site configured and mostly working Except that about 70% of the time when transferring a file the upload will hang forever. If I disconnect the ftp client and reconnect and try to upload the same file I will get an error on the client saying the file is locked. I have to restart the ftp service to clear the lock. I fired up process explorer and did a search on the file in question and sure enough the ftp service has a lock on the file and it takes around 20 minutes to release the lock on its own (and sometimes longer). This lock stays around even after I disconnect the client. Like I said this only happens about 70% of the time, the other 30% of the time it goes through just fine. Things i have verified. -Not a firewall issue. Server is using passive port range 8000-9000 which is allowed on the firewall. -Not a nat issue, server has a globally rout-able ip address -all recommended/required updates installed I have 5 other servers in a very similar configuration and this is the only one i have problems with.

  • administrator user unable to login, suspicious user accounts "sky$", "admin$"

    - by mks
    I have a Windows 2008 R2 Standard (64 bit) running in a virtual machine. Suddenly from yesterday onwards I am not able to login as administrator. Nobody changed the password. Both in the console as well as using remote desktop I am unable to login. Whenever I login as Administrator I am getting this error: "The user name or password is incorrect" Nothing has changed in the machine and I have logged in the past successfully both through console and via remote desktop several time on the same machine. One strange behaviour I noticed is, I am seeing some additional user accounts if I try to login as other user. The suspicious user account are: sky$ admin$ SUPPORT_388945a0 Is it created by some malware/virus? Or is it some windows hidden account? Microsoft site says that SUPPORT_388945a0 is: The Support_388945a0 account enables Help and Support Service interoperability with signed scripts. This account is primarily used to control access to signed scripts that are accessible from within Help and Support Services. Administrators can use this account to delegate the ability for an ordinary user, who does not have administrative access over a computer, to run signed scripts from links embedded within Help and Support Services. These scripts can be programmed to use the Support_388945a0 account credentials instead of the user’s credentials to perform specific administrative operations on the local computer that otherwise would not be supported by the ordinary user’s account. When the delegated user clicks on a link in Help and Support Services, the script executes under the security context of the Support_388945a0 account. This account has limited access to the computer and is disabled by default. However I am not sure from where this "admin$" and "sky$" came. Anyone has similar experience?

    I have a question about security of a file on a webserver. I have a file on my webserver which is used by my webapplication. It's a bitcoin wallet. Essentially it's a file with a private key in it used to decrypt messages. Now, my webapplication uses the file, because it's used to recieve transactions made trough the bitcoin network. I was looking into ways to secure it. Obviously if someone has root access to the server, he can do the same as my application. However, I need to find a way to encrypt it. I was thinking of something like this, but I have no clue if this is actually going to work: Client logs in with some sort of client certificate. Webapplication creates a wallet file. Webapplication encrypts file with client certificate. If the application wants to access the file, it has to use the client certificate. So basically, if someone gets root access to the site, they cannot access the wallet. Is this possible and does anyone know about an implementation of this? Are there any problems with this? And how safe would this be?

  • How to move Mdadm RAID drive (EBS based) to different AWS Instance

    - by Stanley
    We have a media-rich web application that is hosted on AWS. We have several Web Servers and we have an NFS server. On the NFS server (Linux server) we have several EBS volumes that are mounted and we've used mdadm to implement the different mounted volumes as a single RAID volume. The Web Servers simply access the NFS storage through a mount point. Amazon has now let us know that they will be performing power maintenance on this server in a couple of days time. Since all our media is on here it would render our site unusable for the hours while Amazon is working on it. We want to try and prevent this downtime. I was thinking that we can prevent server downtime by perhaps setting up a new server temporarily and attaching the EBS drives (raid volume) to that server and have our web servers point there during maintenance. This is a very high risk operation since this involves several terabytes of our production data. What would be the safe way to move over our logical raid drive (md0) to a new amazon instance? I was hoping that I could start with building the new server, mounting the ebs volumes and assembling the RAID partition using mdadm --assemble --scan before unmounting from the existing instance so that I can first test that everything works and thus having it mounted on two instances at the same time, but I don't believe that is possible with the way that filesystems work. How do I move a Linux software RAID to a new machine? suggests a way to move drives, but isn't really a cloud-based question. Perhaps there are simpler ways to prevent system downtime with our solution being hosted on the cloud? I have considered taking an EBS snapshot, but that tries to replicate all the many terabytes of mounted storage, so this is not a practical solution. Any ideas?

  • How to configure IIS 7.5 to allow special chars in Url for ASP.NET 3.5?

    - by Sebastian P.R. Gingter
    I'm trying to configure my IIS 7.5 to allow specials chars in the url for ASP.NET. This is important to support wide-spread legacy url's on a new system. Sample url: http://mydomain.com/FileWith%inTheName.html This would be encoded in the url and requested as http://mydomain.com/FileWith25%inTheName.html This simply works, when creating a new web in IIS 7.5, placing a file with the percentage sign in the file name in the web root and pointing the browser to it. This does not work, however, when the web site is an ASP.NET application. ASP.NET always returns a 400.0 - Bad Request error in the WindowsAuthentication module from the StaticFile handler, when pointing to that url. It however displays the requested url correctly and also resolves correctly to the correct physical file (the information from the field 'Physical Path' from the Server error page points to the physically available file). There are hints on how to enable this, so I followed the instructions on these websites step by step: http://dirk.net/2008/06/09/ampersand-the-request-url-in-iis7/ http://adorr.net/2010/01/configure-iis-to-accept-url-with-special-characters.html The second one actually sums up the information from the first post and adds some more information about x64 systems (we're running x64) and on an additional web.config change for this. I tried all that, and still can't get this running from an asp.net web application. And yes: I rebooted after applying the registry changes. So, what do I have to do in addition to the settings described in above posts, to support the legacy url's which contain percentage characters? Additional info: Application Pool mode is integrated. Push after some days. No idea anyone?

  • Setting up PerformancePoint Services on Sharepoint 2010: connection errors

    I have tried to setup PerformancePoint Services on SharePoint 2010, but every time I try to use the dashboard designer, I get this error: “An error has occurred attempting to contact the specified SharePoint site” I have tried these steps but it hasn't helped.

  • Attempting to set up xampp and zend server on the same machine

    - by umbregachoong
    I am attempting to set up the zend server and xampp on the same machine but I am running into problems. I came across documentation on the zend site that said you cannot do this. However the folks over at apachefriends said you can. I have since discovered that I can run some of the zendframework examples within xampp by downloading the zendframework2 library and the skeleton app from git and I am doing this right now. However, I would like to know how to set them both up without having any conflicts both for the apache2 server and phpmyadmin. (One of the frustrating things is trying to load phpmyadmin in the deployment dialog by using the zpk tool in Zend). What I did in trying to set up both servers on windows 7 is as follows: First I have tried to set up the httpd conf files separately for each server, xampp running on port 8082 , and zend running on port 8088. At the time xampp would work, but zend server would not. This is after setting up the virtual host files separately for each server. Question 1: Where are the zend server error logs? Earlier, I was able to get both of them running configuring the xampp server httpd-conf file alone, however, I experienced problems with phpmyadmin even after configuring phpmyadmin on xampp to work on a different port other than 3306. Second question here: how to set up the two mysql phpmyadmin instances so they do not conflict with each other? Here is the xampp virtual host section: ##ServerAdmin [email protected] DocumentRoot "C:/xampp/htdocs/" ServerName localhost 8082 ##ServerAlias www.dummy-host.example.com ##ErrorLog "logs/dummy-host.example.com-error.log" ##CustomLog "logs/dummy-host.example.com-access.log" common Here is the zend virtual host section: DocumentRoot "C:\Program Files (x86)\Zend\Apache2/htdocs" ServerName localhost:8088 </VirtualHost> I have looked at this httpd.apache.org/docs/2.2/vhosts/ and this http://survivethedeepend.com/zendframeworkbook/en/1.0/creating.a.local.domain.using.apache.virtual.hosts but I am obviously doing something wrong here. I also have the java sdk running on this machine with tomcat and apache and I have no conflicts- too bad this is not the case for zend server and xampp Thanks umbre gachoong

  • Iframe pages on Facebook does not show in Internet Explorer 9 - Windows 7 64-bit

    - by Morten
    Have this very irritating problem with Internet Explorer 9 and Facebook. If I go to Facebook and watch a page with iframes (like IFBML pages) it will not show up in Internet Explorer 9. It shows up in Firefox 4 and Chrome 10, but not in Internet Explorer 9. I run Windows 7 64-bit SP1 (danish). The strange thing is that I own three different PC´s and they all run Windows 64-bit SP1 and all of them has this issue. Can´t figure out what causes this issue. I have tried the following: Uninstalled AVG antivirus and installed Microsoft Antivirus - no change Updated Windows with SP1 - no change Updated from Internet Explorer 9 beta to Internet Explorer 9 final Ed. - no change Emptied cache and temp files in Internet Explorer 9 - no change Made www.facebook.com a trusted site in Internet Explorer 9 - no change And a lot of other things I can not remember I guess....but nothing seems to work. As I´m using quite a lot of my working time developing Facebook Fanpages it is frustrating not to be able to test them in Internet Explorer 9. BTW - it is Internet Explorer 9 32-bit - not 64-bit. Any clues?
