  • HAPROXY per domain redirection

    - by SecondThought
    I'm trying to redirect requests to my load balancer by domain name with acl and hdr_dom, to a separate backend. The redirection works ok with the first request - 'GET /' (the destination server is a WordPress site) but when the client asks for the assets ('GET /blablabla/style.css' for example) the haproxy doesn't redirect it to the right backend anymore, but to the default one, with . In the haproxy log I can see the correct host that the request is for (the one that I defined in hdr_dom) but it's like that since the GET request itself is relative (I mean not containing the domain but only from the /blablabla and forth), haproxy doesn't recognize it with the hdr_dom. I'm just guessing here.. Please help...

  • Windows 2008 RC2 IIS6 SMTP Virtual Servers - Limited to 4

    - by webnoob
    In line with this post: http://www.hugheserblog.com/2012/05/22/error-creating-iis-smtp-virtual-servers/ I am receiving the same issues: When we tried to add more than 4 IIS SMTP virtual servers, we got the error within IIS, “The system cannot find the path specified.” This post is almost 2 years old and my server is up to date with Windows updates so I assumed it would be fixed already. Does anyone know if I need to do something special (ie. contact Microsoft) to get a special fix for this? The information in the post suggests it should have been included in an update.

  • Amazon EC2 Elastic Load Balancing - strategy for zero downtime server restart

    - by Yoga
    I have 5 web servers (Apache/mod_perl) behind Amazon EC2 Elastic Load Balancing, when I deploy codes to the web servers, I am doing this.. For each machine, shutdown the Apache Update the code Start over the server and proceed to the next server I think when my server is shutdown, ELB will not distribute request to my server, but how about the request still serving? I think a better approach is Stop accepting new request from ELB Sleep for sometimes, shutdown web server only if all requests are responded Update the codes Start the server again But how to perform (1) and (2) from my local sever? Do I need to use AWS API? or other easy way to do it? Thanks.

  • Can not access to my apache server remotely

    - by Jichao
    I have bought a VPS server, setted the apache server. But I could only access the webpage from local, I thought maybe the server did not recieveing access from outside. I tried Firefox, but the access_log shows nothing accessed. But telnet http://www.59lt.com 80 and type nonsence code, I recieved following error: and the access_log under /etc/httpd/logs also caught the acess, This proved that the server do access request from outside, so why it ignore the normal request from Firefox, but choosed to recieving request from telnet? Thanks. PS: I'm using CentOS + yum installed apache(just now installed).

  • Application to handle form approval

    - by ChrisMuench
    Hello, Hopefully this is the right place for this question. I have done a fair amount of research and yet to find anything that matches what I want. What I'm envisioning is the following. Let me know if any of you know of a program that will do what I want. Also it must be web-based anom user - fills out form - email gets sent to admin saying xyz has filled out form abc with links to approve/disapprove request. admin can also login and edit form and resent results to original submitter. Also once the admin approves/disapproves request the original submitter gets an approve/disapprove email. and you can search by date submitted, specific project/form, status of request(submitted, approved, disapproved). any ideas all on where I could find this? I started to look into drupal with workflows and actions but it just doesn't flow right for this

  • Slopes in 2D Platformer

    - by Carlosrdz1
    I'm dealing with Slopes in a 2D platformer game I'm developing in XNA Game Studio. I was really tired of trying without success, until I found this post: 45° Slopes in a Tile based 2D platformer, and I solved part of the problem with the bummzack answer. Now I'm dealing with 2 more problems: 1) Inverted slopes: The post says: If you're only dealing with 45 degree angles, then it gets even simpler: y1 = y + (x1 - x) If the slope is the other way round, it's: y1 = y + (v - (x1 - x)) My question is, what if I'm dealing with slopes with less than 45 degree angles? Does y1 = y + (v - (x1 - x)) work? 2) Going down the slope: I can't find a better way to handle the "going down through the slope" situation, considering that my player can accelerate its velocity. Edit: I was about to post a image but I guess I need to have more reputation he he he... What I'm trying to say with "going down" is like walking towards the opposite direction, assuming that if you are walking to the right, you are incrementing your Y position because you are climbing the slope, but if you are walking to the left, you are decrementing your Y position.

  • Adventures in Lab Management Configuration: CMMI Edition Part 1 of 3

    - by Enrique Lima
    I remember at one point someone telling me how close Migrate was to Migraine. This was a process that included an environment from TFS 2008 to TFS 2010, needed to be migrated too as far as the process template goes.  Here we are talking about CMMI v4.2 to CMMI v5.0.  Now, the process to migrate the TFS Infrastructure is one thing, migrating the Process Template is a different deal, not hard … just involved. Followed a combination of steps that came from a blog post as the main guidance and then MSDN (as suggested on the guidance post) to complement some tasks and steps. Again, the focus I have here is CMMI. The high level steps taken to enable the TFS 2008 CMMI v4.2 migrated to TFS 2010 Process Template are: 1)  Backup the Collection, Configuration and Warehouse Databases. 2)  Downloaded the Process Template using Visual Studio 2010. 3) Exported, modified and imported Bug Type Definition 4) Exported, modified and imported Scenario or Requirement Type Definition. 5) Created and imported bug field mappings. Now, we can attempt to connect using Test Manager, and you should be able to get this going. After that was done, it was time to enroll VMs that already existed in the environment.  This was a bit more challenging, but in the end it was a matter of just analyzing the changes that had been made to had a temporary work around from the time we migrated to the time we converted the Work Items and such and added fields to enable communication between the project and the Test and Lab Manager component. There are 2 more parts to this post, the second will describe the detailed steps taken to complete the Process Template update and the third will talk about the gotchas and fixes for the Lab Management portion.

  • MVC design patterns

    - by insane-36
    I have an application and it does not use a very good structure. However it seems to me that I have tried to stick to mvc design pattern but a senior engineer claims that I have no design patterns and code are mesh. How I have structured the code : I have couple of nsmanagedobject model classes which represents model in my case and a reskit library which encapsulates the nsurlconnection and url request. I fetch the request from the view controller itself and then when the request get completed I create predicate and then populate it in tableview. Wherever I need custom view either I create it in nib or create in a custom subclass of UIView. I have use delegation pattern and notification to communication to view controller, views and block callback with restkit. But, the senior engineer is very new to ios. He has been doing it for 2 months now but he is a good java programmer. So, what is mvc pattern ? Is core data model not working as a model objects, view controller as controller and views. I dont seem to find any other places or any other cases to create my own model object since the most of the models are used as NSManagedObject subclass.

  • A tip: Updating Data in SharePoint 2010 using REST API

    - by Sahil Malik
    SharePoint 2010 Training: more information Here is a little tip that will save you hours of head scratching. See there are two ways to update data in SharePoint using REST based API. A PUT request is used to update an entire entity. If no values are specified for fields in the entity, the fields will be set to default values. A MERGE request is used to update only those field values that have changed. Any fields that are not specified by the operation will remain set to their current value.   Now, sit back and think about it. You are going to update the entire entity! Hmm. Which means, you need to a) specify every column value, and b) ensure that the read only values match what was supplied to you. What a pain in the donkey! So 99/100 times, a PUT request will give you a HTTP 500 internal server error occurred, which is just so helpful. Read full article ....

  • Need suggestion for FireFox add-on to simplify tweeting with multiple accounts.

    - by JohnFx
    I've been using the Firefox Shareaholic browser add-on to post links quickly to my twitter account, and am very happy with it. Recently, however, my company has tasked me with updating our corporate twitter account too. Unfortunately, it doesn't seem to offer the ability to register multiple twitter accounts and let you select one when you tweet the current page. I'm looking for suggestions on a browser add-on for Firefox to do just this. Just to be clear, I'm not looking to be able to post a single link to multiple twitter accounts at one time. I just want a one click "twitter this" that lets me pick which account to post it to. Bonus: If you know a workaround to do this in Shareaholic, that would be even better.

  • Wireless slow, but very odd

    - by Logman
    I have a HP Pavilion dv6 laptop, internet through the wireless timeouts. Even though it connects fine to the AP/router. The computer had a virus (searchnu?) and I backed up the usual and restored the laptop to factory image. Problem is after the restore the internet through the wireless the same still... and connected via wired and everything worked fine. I was able to update the whole system. Internet worked perfect, speed great. But the wireless still was pitiful. Ping tests with wireless are interesting: Google= 18ms Gmail= 18ms Yahoo= 1023ms 8.8.8.8=30ms Microsoft= Request Timed Out Bing= Request Timed Out msn= Request Timed Out even though I get 18ms with google, the pages take a long time to load. Is this a root kit? is it the wireless card in the laptop?

    I'm not sure how long this issue has been happening, but recently a few of the remote sales users were going to a sales meeting and wanted to set their Out of Office... however in Outlook 2010, they get this error message: "Your automatic reply settings cannot be displayed because the server is currently unavailable" When I run the Exchange Remote Connectivity Analyzer, Autodiscover completes fine, but the next step fails: Exception details: Message: The request failed.

  • Deal Registration Moves to Oracle Partner Store (OPS)- The Four Action Items for Partners

    - by Richard Lefebvre
    In November 2012, Oracle’s partner deal registration process will move to the Oracle Partner Store (OPS). During this time, OPS will become the single source for partners to register deals, obtain deal status, and place orders. What will partners need to do? 1. Request an OPS Account – If your company is new to OPS the first thing you need to do is request an account (if your company already has an OPS account, go to step 2). It’s important to have the person who will be managing your OPS account make this request as soon as possible. They will be set up as your company’s primary administrator. 2. Set-Up Users in OPS – Setup of users can start immediately, and will be handled by the primary OPS administrator at your company. The process is simple, but all existing users of Global PRM (Partner Relationship Management) deal registration will need to be set up in OPS before November 14, 2012.  3. Review/Action Any Registrations Pending Submission in PRM – Prior to November 14, 2012, all pending registrations should be submitted in the existing PRM system. It is important that this step is complete so registrations will not need to be re-entered when the system is moved to OPS on November 17, 2012. Registrations pending submission are easily identified on the registration listing screen with either “Incomplete” or “Returned to Partner” in the status column.  4. Attend Training – Oracle will offer multiple VAD and VAR training sessions beginning October 29, 2012. It is recommended that all users attend one of these important sessions.  Detailed instructions on each of these tasks can be found on the OPS Information Page. OPS will offer several enhancements to the deal registration process, including: Simplified Registration Form Easier Product Selection Expanded Browser Support Shared Registration Visibility Between VAD and VAR Pre-set Customer Selection From Partner Ordering Base Best Regards, Titina Ott Vice President, Worldwide A&C Systems And Business Processes

  • Best approach for tracking dependent state

    - by Pace
    Let's pretend I work on a project tracking application. The application is a database backed, server hosted, web application. In this application there are Projects which have many Activities which have many Tasks. A Task has two date fields an originalDueDate and a projectedDueDate. In addition, there are dynamic fields on the Activities and the Projects which indicate whether the Activity or Project is behind schedule based on the projected due dates of the child tasks and various other variables such as remaining buffer time, etc. There are a number of things that can cause the projectedDueDate to change. For example, an employee working on the project may (via a server request) enter in a shipping delay. Alternatively, a site may (via a server request) enter in an unexpected closure. When any of these things occur I need to not only update the projectedDueDate of the Task but also trigger the corresponding Project and Activity to update as well. What is the best way to do this? I've thought of the observer pattern but I don't keep a single copy of all these objects in memory. When a request comes in, I query the Task in from the database, at that point there is no associated Activity in memory that would be a listener. I could remove the ability to query for Tasks and force the application to query first by Project, then by Activity (in context of Project), then by task (in context of Activity) adding the observer relationships at each step but I'm not sure if that is the best way. I could setup a database event listening system so when a Task modified event is dispatched I have a handler which queries for the Activity at that point. I could simply setup a two-way relationship between Task and Activity so that the Task knows about the parent Activity and when the Task updates his state the Task grabs his parent and updates state. Right now I'm stuck considering all the options and am wondering if any single approach (doesn't have to be a listed approach) is jumping out at others as the best approach.

  • cookie not being sent when requesting JS

    - by Mala
    I host a webservice, and provide my members with a Javascript bookmarklet, which loads a JS sript from my server. However, clients must be logged in, in order to receive the JS script. This works for almost everybody. However, some users on setups (i.e. browser/OS) that are known to work for other people have the following problem: when they request the script via the javascript bookmarklet from my server, their cookie from my server does not get included with the request, and as such they are always "not authenticated". I'm making the request in the following way: var myScript = eltCreate('script'); myScript.setAttribute('src','http://myserver.com/script'); document.body.appendChild(myScript); In a fit of confused desperation, I changed the script page to simply output "My cookie has [x] elements" where [x] is count($_COOKIE). If this extremely small subset of users requests the script via the normal method, the message reads "My cookie has 0 elements". When they access the URL directly in their browser, the message reads "My cookie has 7 elements". What on earth could be going on?!

  • multi-thread in mmorpg server

    - by jean
    For MMORPG, there is a tick function to update every object's state in a map. The function was triggered by a timer in fixed interval. So each map's update can be dispatch to different thread. At other side, server handle player incoming package have its own threads also: I/O threads. Generally, the handler of the corresponding incoming package run in I/O threads. So there is a problem: thread synchronization. I have consider two methods: Synchronize with mutex. I/O thread lock a mutex before execute handler function and map thread lock same mutex before it execute map's update. Execute all handler functions in map's thread, I/O thread only queue the incoming handler and let map thread to pop the queue then call handler function. These two have a disadvantage: delay. For method 1, if the map's tick function is running, then all clients' request need to waiting the lock release. For method 2, if map's tick function is running, all clients' request need to waiting for next tick to be handle. Of course, there is another method: add lock to functions that use data which will be accessed both in I/O thread & map thread. But this is hard to maintain and easy to goes incorrect. It needs carefully check all variables whether or not accessed by both two kinds thread. My problem is: is there better way to do this? Notice that I said map is logic concept means no interactions can happen between two map except transport. I/O thread means thread in 3rd part network lib which used to handle client request.

  • How to configure my web server for public and development service

    - by Steve
    I have one and only one web server, which runs Windows Server 2008 and wamp. Now I would like to setup SVN on the server so I can program the trunk version of the website. Every time I branch a version and put it to public. While developing on the trunk version, I also want to be able to test it. The web server has 5 IPs so I can use one IP for public website(the branch) and another IP for trunk development test. I believe one wamp server can only handle one 80 port request thus can only handle one website. How can I configure the server so it can handle one IP request and direct to my branch and handle another IP request and direct to my trunk?

  • C++ Parallel Asynchonous task

    - by Doodlemeat
    I am currently building a randomly generated terrain game where terrain is created automatically around the player. I am experiencing lag when the generated process is active, as I am running quite heavy tasks with post-processing and creating physics bodies. Then I came to mind using a parallel asynchronous task to do the post-processing for me. But I have no idea how I am going to do that. I have searched for C++ std::async but I believe that is not what I want. In the examples I found, a task returned something. I want the task to change objects in the main program. This is what I want: // Main program // Chunks that needs to be processed. // NOTE! These chunks are already generated, but need post-processing only! std::vector<Chunk*> unprocessedChunks; And then my task could look something like this, running like a loop constantly checking if there is chunks to process. // Asynced task if(unprocessedChunks.size() > 0) { processChunk(unprocessedChunks.pop()); } I know it's not far from easy as I wrote it, but it would be a huge help for me if you could push me at the right direction. In Java, I could type something like this: asynced_task = startAsyncTask(new PostProcessTask()); And that task would run until I do this: asynced_task.cancel();

  • How to add recently set cookies to nginx's access log

    - by etoleb
    I'd like to include cookie data in an nginx access log like so: (simplified example) log_format foo '$remote_addr "$request" $cookie_bar'; access_log /var/log/nginx/access.log foo; This works great on requests that already have a cookie "bar", but for the first request to my server nginx will report "-" as the value of "bar". It seems like my problem is that nginx is looking at the request headers for the cookie value. Is there a way check for a Set-Cookie in the response and use that as a fallback?

  • Handling timeout in network application

    - by user2175831
    How can I handle timeouts in a network application. I'm implementing a provisioning system on a Linux server, the code is huge so I'm going to put the algorithm, it works as like this Read provisioning commands from file Send it to another server using TCP Save the request in hash. Receive the response then if successful response received then remove request from hash if failed response received then retry the message The problem I'm in now is when the program didn't receive the response for a timeout reason then the request will be waiting for a response forever and won't be retried. And please note that I'll be sending hundreds of commands and I have to monitor the timeout commands for all of them. I tried to use timer but that didn't help because I'll end up with so many waiting timers and I'm not sure if this is a good way of doing this. The question is how can I save the message in some data structure and check to remove or retry it later when there is no response from the other end? Please note that I'm willing to change the algorithm to anything you suggest that could deal with the timeouts.

  • Regarding the functioning of the HTTP server

    - by Luv
    As all of us uses the HTTP protocol for accessing the web, and request at the port number 80 of the server, now suppose i want to browse or download a file then i will request to the HTTP server by specifying the complete URL. If the server is having file, it would return it if it is not having the file then what will it do? I think it will make the request to the appropriate server which would be having this file and get the file and return to us. In this way does the HTTP server acts as an intermediate between the client and the server? Please correct me if i am wrong here. Many many thanx in advance

  • "private" directory not accessible in Apache

    - by janeden
    The directory private lives under my DocumentRoot, and despite its name, it should be accessible just like any other dir. But if I add the following RewriteRule to httpd.conf: RewriteRule ^/([^\.]+)$ /$1.html [L] Apache returns 403 for http://server/private/2201. The error log states client denied by server configuration: /private/2201.html If I then rename private to foo, or if I request 2201.html directly, the file is served: 127.0.0.1 - - [21/Nov/2011:10:24:45 +0100] "GET /private/2201 HTTP/1.1" 403 214 127.0.0.1 - - [21/Nov/2011:10:24:58 +0100] "GET /foo/2201 HTTP/1.1" 200 3068 127.0.0.1 - - [21/Nov/2011:10:27:39 +0100] "GET /private/2201.html HTTP/1.1" 200 3068 This is confusing. Is there any special rule for directories named private? If so – why does the direct request for 2201.html work (although the denied request seems to handle the same resource, at least according to the error log entry)?

  • Is it safe to Update and/or Insert records into an accounting software's database? (Pastel Evolution)

    - by user1020317
    Our CRM system can post transactions to our accounts software (Pastel Evolution), but it doesn't perform the required currency conversion. Both systems have different "base" currencies (because of our location), so the figure thats sent to Pastel evolution is right, but it is reflected in the wrong currency. The CRM uses an ODBC connection to post figures to Evolution. I can make a tool which sits between the two systems which can update and/or insert the transactions into Pastel, by mimicking what the CRM would have done if it was doing the POST. Is it safe for me to mimic and/or update these transactions directly in the Pastel database? Is it common for important validation to be performed in the ODBC layer, and if so, can I tap into an applications ODBC, or is there a custom driver built by the CRM to communicate with the DB?
