Mar 10, 2013
I have developed an online exam application in college where we fix the timing for an exam the students conduct there exams at that time. this application is stored in local iis server in the college. i am using inproc session. here there are 200 students writing exam at a time .the problem is the browser stuck after some time and not resopnce unless we restrart the iis on the server. i checked the windows even log .the warning details are listed below. my question is ,is the inproc session is ok for here or i need to use the sql server session or state server session ...

I'm having a problem with file streaming where this file is a video that is streamed to a FLV player.
Essential components for understanding the problem:
- An asp.net page called Viewer.aspx that has de FLV player incorporated in the HTML.
- An asp.net page (It could be an http handler but in this case it's not) called Downloader.aspx that gets a flv file from somewhere on the web and writes it to the Response Output Stream.
Everytime Viewer.aspx is called, it makes Downloader.aspx the source of the the FLV player and the video is correclty presented and streamed into the player.
The problem I am having now is that any user interaction with the page (even typing an URL inside the same website domain on the browser address bar) becames hung until the video download ends.
I can measure this video download with HTTP Watch for example, and confirm that just after the video download into the player ends, the command issued by the user is immediately processed (or the browser goes to another page if the user typed a new address in the browser address bar).
I tought that it could be the limit of 2 connections per domain, but HTTP Watch only shows one active connection (the video download into the FLV player).
Even if it was this 2 connections limit, I think a nice solution would be to somewhat detect the user interaction with the page and abort that video download.
I am trying to register the route collection in .net based on each session. The code I have works fine, you goto website/username and it loads the correct sub pages, but you have to restart the application to goto website/username2 to load those sub pages. But when the application is restarted the second one works, but then not the first one. Is there some way to create a different route collection per session not per application using system.web.routing.
Developing a website in ASP.net. On the development site all is working fine.We decide to publish the site using visual studio 2008's publish mechanism.The publish goes flawless.When we go to the live site, it hangs anywhere from 2 minutes to 30 minutes before it starts serving pages.All other sites on the same server seem to work fine.If we reboot the server it starts serving pages right away.It is not a programming issue, as once the site kicks in all seems to work fine.VS 2008, .NET 3.5, On both IIS 6.0 and 7.5
I have a server running Windows Server 2003 R2 Standard Edition (Service Pack2) and our IIS server is hosting about 20 different asp.net websites. I've never noticed this in the past, but when I debug an application and it stops at a breakpoint, the other websites hang as well. If I try to go to any of the other websites, then I just get a while page that's loading until i pass the breakpoint or I stop debugging.Does this have anything to do with application pools and if so, how do i fix it? Or if it does not, any ideas on how to fix this issue? I find myself debugging my apps often and I can't bring down all other applications when I do it.
I'm currently in the process of deploying my C# website. In the development IDE everything works fine but when i deploy to ISS 7 some of the pages work fine but others will just randomly hang. Ive been using the tracing utility and debug code to see where the problem is occurring. This is where it gets weird. If I turn on the tracer and set the pageoutput to true it works as fast as it does in the IDE without the hangs but displays all the tracing information. If i set the pageoutput to false and leave the tracer on, it will return to having the same problem. Ive put time outputs through the system and everything is running through quickly. So im at the point now where if i have the tracer displaying on the website there is no problem. But if i don't display the tracer the problem occurs and i cant see the logs to pinpoint it. The problem is occurring after EndRender. Sometimes it loads the top of the page and then hangs. The pages do complete but can take up to 10 seconds. . The same problem is happening in both IE and firefox.
I guess my question is how do I disable this feature. I understand it's useful to have so that session state can be more predictable, however in my case a long running reports page load is killing users' ability to multitask.
in one request i am updating session variable. in the other request, i am trying to access that session value, but it was blocked until the first request finish. I am using C# with ASP.NET 2.0 UPDATE: My page code looks like this.
concerning requests being blocked from a main window after a popup window had initiated a file download. Further requests from the same session are being queued until the download is complete. So, is there any way to override this? Is there anyway to tell asp.net to not serialize same session requests? Is there any way to tell asp.net to ignore session for a specific request...httphander(module) or otherwise?
why requests from the same session are being queued until the download is complete. please tell me the funda behind it and how to overcome it.
What is the right approach when users (authenticated domain admins) should be able to start batch jobs (usually exe files) from an IIS (7.x) aspx (c#) page? This is an intranet site. The batch jobs have to run on the web server as Domain Admins. The website pool is executed by network service or some similar restricted account in AD.
Approaches I can think of (and their disadvantages): 1. Start exe file with System.Diagnostics.Process.Start with another account. This feature is disabled in IIS 7.x, how do I allow it?
2. Create a sheduled task and call scheduled task-api. This unmanaged dll is giving VS compiler warnings because it's unsafe to call from managed code.
3. I suppose there's a better approach, because the previous suggestions doesn't appear safe or robust.
I have been spending a better part of a week trying to track down why I am not able to clear all session variables in a web app (vs 2010, vb.net). What I have tracked it down to is that when I remove or abandon sessions that my html pages or codebehind access, it works, but for some reason in any of my class files where I use "Public Shared strConnection as String = HttpContext.Current.Session("strConnection").ToString" to access a session variable, it finds the old one and not the current one. I have to wait for it to time out, go in again, and it will find the new one.
I do not use Linq, and there is only one place in the whole web app that I place the connection string in a variable whcih is when a person logs in. It points them to the correct database. The sqlconnection is set for all of my listviews in Page_Init to make sure that they aren't using any session variable that they create on their own. Interestingly enough that if I use debug to go in each time, exit debug, enter debug again trying to access a different database, it works correct each time. I assume that debug is correctly killing the session variable for the classes for me.
I developed and deployed a web application using ASP.NET,C# successfully. The application was running perfectly until few days back. [NOTE: It still works fine on local machine (tested using both development server and IIS)] What happens now is: The website opens perfectly. After few operations which involves database interactions, in all the pages, the pages stop responding. I mean, after a few clicks, if I try another operation the page starts postback for unlimited time period and never gets rendered and a following message is given: The connection was reset: Firefox 3.5... IE cannot display the web page: IE 7, 8 There is no database connectivity issues. I checked event logs on the web server and found few unhandlled exceptions, I corrected those. Now the event log doesn't show any error. But the problem is same.
I tried accessing the page from web server's browser, everything works fine. Even my boss can browse all pages with no problem (both have Win Server installed). Other machines (mostly XP) can't browse after sometime(as described above). I checked the memory usage, cpu time - NO ISSUES.
i have 1 master page with 5 pages that call it. now on the master page, I have few dropdowns and textboxes, and the calling pages only have a small article in the corner. I want to start a session on page_load event, so that if the user chooses to select a dropdown or put data in textbox, even if he clicks on the other 4 links of other pages, the data should stay.
If i am using Session management in my asp.net website, when does the session start, i.e. will the session start as soon as any user hits the website or does the session start only when we put some data into the Session?
I want to initiate a class for each user at the start of the user's session so that a single class can be used throughout the user's session. I checked out this post but I'm not sure where I should be placing this Sessionhandler class. Inside global.asax? How do I go about accomplishing this?
