• In IIS why do HTTP requests use the host header, and FTP requests do not

  - by Keeno

  So.... In IIS, if you use the in-build FTP you need to combine the FTP host header in the FTP username e.g. www.hello.com|domain/username So, the FTP program gets its "hook" from the username. However, you can connect to the FTP site using www.hello.com:21 over the FTP port. Why then, doesnt the FTP service work the same way as the HTTP service? IIS knows what site to serve back based on the host header after all.... Thanks!

• How many of you *really* surf around without JavaScript enabled? [closed]

  - by Stephen

  I've decided to rephrase the question. After some deliberation on Meta, I've realized that my question needs to be a bit more focused. The question: Should we (web developers) continue to spend effort progressively enhancing our web applications with JavaScript, ensuring that features gracefully degrade, thereby ensuring accessibility? Or should we spend that time focused on new features or other areas of development? The subtext of that question would be: How many of our customers/clients/users utilize our websites or applications with JavaScript disabled? Do you have any projects with requirements that specifically demand JavaScript functionality (almost all of mine do), and do those requirements also demand graceful degradation? For the sake of asking this question, I pulled up programmers.stackexchange.com without JavaScript enabled, and I was greeted with this message: "Programmers - Stack Exchange works best with JavaScript enabled". It was difficult to log in, albeit the site seemed to generally work okay. (I wasn't able to vote up any questions.) I think this is a satisfactory approach to development. Imagine the effort involved in making all of the site's features work with plain old HTML and server-side logic. OTOH, I wonder how many users have been alienated by this approach. We've all been trained (at least the good developers among us) to use progressive enhancement and to ensure our web applications' dynamic features degrade gracefully. Is this progressive enhancement just pissing into the wind, or do some of our customers actually utilize certain web services without JavaScript enabled? I mean, like really, not figuratively or presumptuously.

• Formatting: Group Multiline Alignment - Added

  - by Petr

  One week ago I have added two new properties for formating PHP code into NetBeans 7.1. In Alignment category there are new properties for Group Multiline Alignment - Assignment and Array Initializer.  The Assignment property influence position of the char '=' in a group of lines with assignments.  Let see the pictures below.  On the left site -  Assignment property is off and on the right site the property is on. As you can see, when the property is set on, then the assignment char '=' is placed after the longest identifier in a group. The group is defined as a number of lines that contains the same type of assignments. End of a group can be empty line, line where is only a comment, different expression, end of a block. This formatting options works for variable assignment, field initialization and constants.  The second new property is for Array Initializer.   Both properties are switched off by default. If you will play with it, please file any problem into our Bugzilla.

• Plesk directory structure problems

  - by johnnietheblack

  I have an entire website with the following directory structure: /example.com /html (public) /css /js index.php /lib session.php other_lib_files.php /views index.php /models /controllers As illustrated, the html is public, and anything above it is private. My site now needs to upgrade servers, and the new server (Linux w/ Plesk) has the following structure (reduced to the problematic parts below): /myplesksite.com /httpdocs /css /js index.php /private /lib /models /views What I would THINK is that I should be able to put my /lib, /views, /models, etc in the directory directly above /httpdocs, the same way I had it in my previous server. Is that possible? Or do I have to put it in private? I would really love not to have to adjust my internal paths throughout the site if not necessary...

• DNS NAmeserver Aname and cname records [closed]

  - by David

  I am inexperienced in the configuration of DNS and have an issue with dominan hosting set up. I have two domains 'www.mydomain1.com' and 'www.mydomain2.com', with mydomain2 pointed at the same place as mydomain1. The domains were passed to me recently by the person who previoulsy controlled them. I have an account with Fasthosts in the UK. When I accepted the domains I could not access the DNS settings and inquired with fasthosts as to why. The reply was: The delegate hosting option for both domains were enabled and this is the reason why you were unable to find the option to edit the advanced DNS records. I have now disabled the delegate hosting option so you can now edit the advanced DNS records for both domains in your account. When I log into the Fasthost control panel now I can access the DNS controls but both domains have no A record or Cname record set up. I am concerned that Fasthosts have blatted the previous Nameserver entries and set me up on theirs but not added any record. 'www.mydomain1.com' currently still works but 'www.mydomain2.com' does not find the site anymore. I am worried I will lose mydomain1 to as the DNS changes filter through the system. my webhosting is at 'xxx.xxx.xxx.xxx/mydomain1.com/' and this is where I want both domains to point. Any advice would be much appreciated. One thing which is confusing me is that because I am on a shared server I have to put 'xxx.xxx.xxx.xxx/mydomain1.com/' to get to my site rather than just 'xxx.xxx.xxx.xxx'. The form on Fasthosts for the A name record only allows an IP to be entered - does it add the mydomain1.com/ onto the end itself? Thanks for any help given - I'm quite worried about this David

• Website restyle, SEO migration plan?

  - by Goboozo

  I am currently in a project for one of my biggest clients. We have built a website that will -replace- the old website. When it comes to actual content its is largely the same. However, the presentation of the content has changed drastically. From our point of view much more user-friendly (main reason to update the site). Now, since the sites presentation has changed we have some major changes in: HTML & CSS: To change the presentation of the content URL's: To make them better understandable (301 redirects have been taken care of and are in place) Breadcrumbs: To enhance the navigation (we have made the breadcrumbs match exactly with the url's) Pagination: This was added to enable content browsing Title tags: Added descriptive title tags to the major links and buttons. Basically all user content including meta tags have remained the same. Now since this company is rather successful and 90% of its clients come from Google's organic results I am obliged to take all necessary precautions. People tell me I need a migration plan to prevent the site being hurt in Google, but I have never worked using such a plan... ...So, based on the above. Would you consider a migration plan necessary and what precautions/actions would you recommend to prevent us being put down in our SERP positions? Many thanks in advance for your answers.

• Cloud computing - database loading question

  - by workwise

  Following is the situation, I want to know whether what I want is possible in cloud computing and is it the best way for me: 1) My main site has a Database with tables with millions of rows, and entries are added almost every second. 2) I will setup a mysql mirror, so there will be a backup database always in sync with the main one. 3) There are few tens of thousands of images- growing. So say total size of images few tens of gigabytes. I will be keeping the image data also in sync on the backup server. 4) There can be short periods where traffic can go 100X the average traffic. 5) I will be using memcache heavily - most database and even frequently used disk files/images will be in RAM. I want that the main site runs on a dedicated server. The backup server is say an Amazon EC2 instance. Now note that since it is live backup, I need to run a small instance continuously. I want that when I anticipate high traffic, I should be able to run a large instance on the cloud and transfer the traffic there. The main point is - I do not want to spend time in "loading" the database on the large instance, as it typically can take few minutes or even hours (experience). So is it possible to just scale the memory/CPU on demand, and not having to load the database or sync up the filesystem? I want to setup my backup scripts etc just ONCE. Thanks JP

• is it possible to use shopify for just their shopping cart component or should I just roll my own

  - by timpone

  I'm working on an e-commerce site and am a rails developer; due to the nature of the items, I am managing them in their own database so I'm really looking for something that is only for the shopping cart aspect (there are things like heavy nesting and integration with other pieces of the app that would be very difficult to reproduce). It seems like there are two ways that I can go. (1) One way is rolling my own shopping cart and using something like Stripe (which I have been evaluating and am working fine with it). This literally could be as easy as creating an orders table and a line items table and a lot of front-end. (2) Or I could try to integrate into a third-party shopping cart like Shopify. I am not really sure if I can just use the shopify shopping cart or whether there is any advantage to this. If I already have most of my app done, would shopify (or another shopping cart app) provide any significant benefit (it clearly could)? Or would the integration be too much of a headache? Like for example, when a user 'adds to order' on my site, can I post to shopify and associate it with that user? thx

• Replacing hyperlinks in Apache2 ProxyPass

  - by Jeroen

  I am using Apache2 with mod proxy on Ubuntu 12.04 as a reverse proxy to some back-end server: <VirtualHost *:80> ProxyPass / http://somewhere.com/mysite ProxyPassReverse / http://somewhere.com/mysite ServerName www.mysite.nl ServerAlias mysite.nl *.mysite.nl </VirtualHost> However, unfortunately the back-end server has some internal links hardcoded; e.g. a link to somewhere else in the site has <a href="http://somewhere.com/mysite/something"> instead of just <a href="something.png">. Is there a way I can use Apache to replace strings in the body as served by the backend before passing it back to the client? E.g replace all instances of "http://somewhere.com/site/" with "http://mysite.nl/" ? I know nginx or so is better as a reverse proxy, but the server is hosting other stuff so port 80 needs to be Apache2.

• Help with "advanced" shell scripting | how to create an image preview of a pdf

  - by lucapozzobon

  First of all, sorry for my english: i'm not british/american. Here is my problem. I've got a folder named pdf with lots of files pdf inside it. I've got another folder named thumbnail, which is empty. I want to create jpg images preview of each pdf to use them in my HTML webpages as previews of the pdf. To do this I'm using a software called IMAGEMAGICK. I tried to put the code inside my PHP files to get the purpose, but it doesn't work. As you understood, I have created a small search engine with apache, mysql to search for pdf locally (offline). Now I want to add a "preview" of the first page of pdfs. Instead, it works by bash command line and the code is: convert pdf/name_of_the_file_pdf.pdf[0] name_of_the_imagefile.jpg (The zero stands for that the image is taken from the FIRST page of pdf) How can i make a script that takes each name of pdf files and put it into that code???? To list all the file, I did ls >pdf but with the little knowledge I have I can't go further.... Some pdf's names contain spaces....Is that a problem? PDF files are so many that i can't do the task typing every name,it wouldn't be a nice and clever work!!!! Thanks a lot in advance!!!

• Solution to route/proxy SNMP Traps (or Netflow, generic UDP, etc) for network monitoring?

  - by Christopher Cashell

  I'm implementing a network monitoring solution for a very large network (approximately 5000 network devices). We'd like to have all devices on our network send SNMP traps to a single box (technically this will probably be an HA pair of boxes) and then have that box pass the SNMP traps on to the real processing boxes. This will allow us to have multiple back-end boxes handling traps, and to distribute load among those back end boxes. One key feature that we need is the ability to forward the traps to a specific box depending on the source address of the trap. Any suggestions for the best way to handle this? Among the things we've considered are: Using snmptrapd to accept the traps, and have it pass them off to a custom written perl handler script to rewrite the trap and send it to the proper processing box Using some sort of load balancing software running on a Linux box to handle this (having some difficulty finding many load balancing programs that will handle UDP) Using a Load Balancing Appliance (F5, etc) Using IPTables on a Linux box to route the SNMP traps with NATing We've currently implemented and are testing the last solution, with a Linux box with IPTables configured to receive the traps, and then depending on the source address of the trap, rewrite it with a destination nat (DNAT) so the packet gets sent to the proper server. For example: # Range: 10.0.0.0/19 Site: abc01 Destination: foo01 iptables -t nat -A PREROUTING -p udp --dport 162 -s 10.0.0.0/19 -j DNAT --to-destination 10.1.2.3 # Range: 10.0.33.0/21 Site: abc01 Destination: foo01 iptables -t nat -A PREROUTING -p udp --dport 162 -s 10.0.33.0/21 -j DNAT --to-destination 10.1.2.3 # Range: 10.1.0.0/16 Site: xyz01 Destination: bar01 iptables -t nat -A PREROUTING -p udp --dport 162 -s 10.1.0.0/16 -j DNAT --to-destination 10.3.2.1 This should work with excellent efficiency for basic trap routing, but it leaves us completely limited to what we can mach and filter on with IPTables, so we're concerned about flexibility for the future. Another feature that we'd really like, but isn't quite a "must have" is the ability to duplicate or mirror the UDP packets. Being able to take one incoming trap and route it to multiple destinations would be very useful. Has anyone tried any of the possible solutions above for SNMP traps (or Netflow, general UDP, etc) load balancing? Or can anyone think of any other alternatives to solve this?

• How important is graceful degradation of JavaScript? [closed]

  - by Stephen

  Should web developers continue to spend effort progressively enhancing our web applications with JavaScript, ensuring that features gracefully degrade, thereby ensuring accessibility? Or should we spend that time focused on new features or other areas of development? The subtext of that question would be: How many of our customers/clients/users utilize our websites or applications with JavaScript disabled? Do you have any projects with requirements that specifically demand JavaScript functionality (almost all of mine do), and do those requirements also demand graceful degradation? For the sake of asking this question, I pulled up programmers.stackexchange.com without JavaScript enabled, and I was greeted with this message: "Programmers - Stack Exchange works best with JavaScript enabled".

• Setting up nginx as proxy to apache; All good, but nginx doesn't serve media

  I have set it up such that nginx proxies request and sends django requests to apache and serves media itself. Following documents my setup: Nginx Configuration: /etc/nginx/nginx.conf user www-data; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; access_log /var/log/nginx/access.log; sendfile on; tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; tcp_nodelay on; gzip on; include /etc/nginx/sites-enabled/*; } ===== ngnix proxy /etc/nginx/proxy.conf ============ proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; =========== Nginx server file: /etc/nginx/sites-enabled/some-name.txt ========== server { listen 208.109.252.110:80; server_name netconf; autoindex on; access_log /home/site/server_logs/nginx_access.log; error_log /home/site/server_logs/nginx_error.log; location / { proxy_pass http://127.0.0.1:80/; include /etc/nginx/proxy.conf; } location /site_media/ { root /home/site/folder/static; } } ========== Nginx very well proxies the request and passes to apache, the required requests, but doesn't serve the media. In the last server file, location site_media is not served, at all. :( Everything seems perfect to me. What is wrong? Thanks in advance.

• create new subdomain or buy new domain? seo costs [migrated]

  - by greek_no_money

  If I am targeting the same audience, but the new sub-site has different concept from the existing site, should I create a new sub-domain or create a new domain? What are the seo advantages and disadvantages of creating a new sub-domain? For example Stack Exchange with Alexa rank 1.474 right now, has sub-domains such as programmers.stackexchange.com and other domains such us serverfault.com with rank 3.515 and stackoverflow.com with rank 109. So why didn't Stack Exchange put, for example, Stack Overflow in a sub-domain to create a better ranking?

• 500 Error when using custom account for application pool in IIS 7

  - by Brownie

  I have a very simple site with only static files in IIS 7 on Windows Server 2008 SP2. When I try to access any static file I get a 500 error. If I rename an html file to have an aspx extension it works fine. The site also works fine when using the built in identity for the application pool. The problem occurs when I switch to using a custom account for the application pool. I have tried using both local and domain accounts to run the application pool under. I have given full control to these accounts on the website directory and files. Turning on tracing reveals this error message: ModuleName: IIS Web Core Notification: 2 HttpStatus: 500 HttpReason: Internal Server Error HttpSubStatus: 0 ErrorCode: 2147943746 ConfigExceptionInfo Notification: AUTHENTICATE_REQUEST ErrorCode: Either a required impersonation level was not provided, or the provided impersonation level is invalid. (0x80070542) I have not had any luck with googling the error code.

• Forwarding a subdomain to main domain using Godaddy

  - by Ryan Hayes

  I have current blog, which was hosted on Tumblr at http://blog.ryanhayes.net. I'm moving it over to http://ryanhayes.net, and have all the 301 redirects set up for the blog entries to map to my new blog, which is hosted using Godaddy (domain included). When I try to set up a subdomain forward, I'm greeted with a nice 403 Forbidden response (as of this writing, you can see it at http://blog.ryanhayes.net. When I try to ping both the subdomain and domain, they point to the same IP address, so I know blog subdomain has at least switched over to point to the same content. I don't really understand why I would get a 403 Forbidden on the same content that I can see perfectly fine via another domain. Currently, I have a CNAME of blog pointing to @, which is how "www" is set up to forward, so I'm assuming it would do the same thing. My question is what is the proper way to set up my DNS to make the blog subdomain forward to my main domain (301) using the GoDaddy DNS manager? Bonus: What is the background on why I am getting a 403 error the current way? Forbidden You don't have permission to access / on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. UPDATE 12/7/2010 Error on site has been fixed, you can no longer view it from my site.

• How to Configure IIS 7.5 to Host Several Classic ASP Sites using 1 IP Address?

  - by SidC

  We are running Windows Server 2008 R2 with IIS 7.5 and have 4-5 Classic ASP sites to install. The main site is stored in wwwroot and the other sites are stored in folders below wwwroot. We have 1 IP address for the server. How do I configure IIS to allow folks to browse/test the sites before domain names are pointed to te server? When I setup one of the sites in a subfolder of wwwroot and assign a separate port to it, I receive a message stating: Config Error Cannot add duplicate collection entry of type 'add' with unique key attribute 'value' set to 'index.asp' How do I remedy this error and permit IIS to render the site?

• What techniques would you use for a next generation java web application?

  - by jakob

  I'm working at a site similar to Foursquare and Yelp, with approximately 100000 unique requests each week that generates content, growing steadily. We are currently using: Seam as Java web framework. MySQL as DB Hibernate as ORM Hibernate Search as Index EhCache for Caching. Since our site is slowly growing out of the current setup and has a lot of legacy code, it is time for us to start thinking about a major refactoring/changing setup. Web framework We are not ready to change the language but we are leaning towards Spring Web Framework, since: Seam is no more. Almost all of us have worked with Spring and liked it. DB and ORM We have done a little research and we are thinking about MongoDB. Index Do we need to have a separate Index if we use MongoDB? Cache ? So my question is basically: If you take Spring Web Framework and MongoDB into consideration, how would a good setup be for a web application that is growing and handles a lot of logged in users generating input and performing searches?

• new project; entire node.js app

  - by Jared

  I have been looking into Node.js, express and Nowjs and love how easy it is to have real time interactions between clients. My background is mostly from CodeIgniter MVC using PHP and MYSql. I want to re make a current web project of mine from scratch to make everything better and more real time with this newer technology. After researching and doing test examples I want to use node.js , express and Nowjs for the real time interactions once someone connects to the socket.io to pull data back to clients. But use Code Igniter for the control of the site and user management , possible shopping cart/store , pretty much everything else. This is purely due to time constraints and that I am already familiar with doing it that way. I have been looking at MongoDB as an alternative to MySql, Basically the app is going to be multiple chat rooms all on one page. with the ability of notifications and private messaging. Lots of data transfer and images. before I started piecing it together I wanted to get people who have already done something similar. My model would use Code Igniter and MySQL to render the page and then connect them onto a node.js server and broadcast using express and nowjs would using a mongoDB be better than mySQL for tons of messages and data being stored or MYSQL? Also does it make since to not make the whole site on Node.js , kinda piece it together like that? I was asked to re post this somewhere else as it was not up to the format for SO, OP from here http://stackoverflow.com/questions/12649469/new-project-need-some-start-up-advice-node-js-app#comment17062924_12649469

• Adsense-type services without the content check?

  - by Ryan Ahearn

  Are there any ad-placing services that don't mind that the page is nothing but a page of ads? Someone else with a .cn tld is pointing to my IP address. I currently have that site on its own name based virtual host that responds to every request with a 403, but I figure if I am paying for the incoming bandwidth, I might as well try to make some money off it. I don't want to actually create any content for this site, which prevents me from using adsense. My only requirements are that it is free for me to sign up and that they don't mind the lack of content.

• [SOLVED]Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel

  - by kazim sardar mehdi

  Another version of this product is already installed.  Installation of this version cannot continue.  To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel I tried to install a new version of windows services that packed into 1 setup.msi and encounter the above mentioned error. To resolve it I tried google read lots of but then find the following article MSIEXEC - The power user's install steps to solve the error: 1. Execute the following command from command prompt: msiexec /i program_name.msi /lv logfile.log where program_name.msi is the new version /lv is log Verbose output   2. open up the logfile.log in the editor 3. find the GUID in it I found it like the following Product Code from property table before transforms: '{GUID}' 4. Above mentioned article suggest  to search it in the registry but to find the uninstall command. Try if you like to see it in the registry. you need to search twice to to get there there you I tried the following command as it mentioned in the above mentioned article but it didn’t work for me. so I keep digging until I got Windows 7 and Windows Installer Error “Another installation is in progress” It mentioned the use of msizap.exe 5.   by combining the commands from both the articles I able to uninstall the service successfully execute the following command from the visual studio command prompt if you already have installed or get it from Microsoft website http://msdn.microsoft.com/en-us/library/aa370523%28VS.85%29.aspx   msizap.exe TWP {GUID} it did the trick and removed the installed service successfully
