Prevent GET Request Timeout?
Jan 19, 2010
I've got an ASP.NET application that serves MP3 content, but that content is generated during the request and can delay the sending of the response's first byte by several minutes.
The client is a podcatcher (I don't know which), and the lowest timeout I've seen is 20 seconds. That is, these clients are (reasonably enough) giving up relatively quickly, assuming there's no response coming.
How can I keep these clients from giving up? How can I let them know a response is coming?

I have an ASP.Net application that makes an AJAX request to retrieve at report. The report can run for a long time so I set the asyncpostbacktimeout in <asp:ScriptManager /> to 600. However, when I try to run the report, if it runs for longer than 90 seconds it fails to come back. I can see in the IIS logs that the POST request succeeded with a 200 status and I can see the time taken is much less than 600.
The web page dutifully waits for the entire 600 seconds before returning with a timeout error:
Error:
Sys.WebForms.PageRequestManagerTimeoutException:
The server request timed out.
Is there any setting I should be checking in IIS? Connection timeout is 900 seconds.

I'm researched how about prevent session timeout, I tested the solutions links bellow and it works great.
http://www.primaryobjects.com/CMS/Article86.aspx
http://www.codeproject.com/KB/session/Reconnect.aspx
But my Website has one thing that still causing problems... the Website calls an ActiveX. Some time in the user navigation the user clicks in a button and a JavaScript loads an ActiveX with the code bellow.
var objDownload = new ActiveXObject('XXXXXX');
objDownload.ActiveXMethod();
This ActiveX makes a huge processing and this is why I'm want the trick to avoid the session expires. I tested the both above solutions but when the ActiveX is running no refresh happens. Can anyone help with this problem? How the ActiveX can be running and the IE makes the refresh?

How to prevent Session.Timeout extension on certain event from codebehind?
What I do - I have Session Timeout configured in Web.config file for 10 minutes. Also, I have in my webpage1.aspx, an ASP.NET AJAX control ModalPopup which shows into the page 9 minutes after the user stopped sending requests to webpage1.aspx. I did this with this code:
[Code]....
[Code]....
So, my initial calculations was that 1 minute before the session ends, i'll inform the user something with the ModalPopup. The problem is that when this Timer1_Tick event triggers, the session.timeout renew ( or extends ) and the session ends 10 minutes later (if user still don't send any request from his browser).
Can I write code in Timer1_Tick event which prevent session extension?

since a have an app, that makes heavy use of AJAX (jQuery), I faced a problem of session timeout.
After a little bit of googling I found something like :
[Code]....
In the refresh page I have just this code :
[code]....
jQuery indeed calls refresh page, writes "success", however- session times out.
Am I doing wrong something? Is there a better way to prevent session time out?

I have an ASP.NET web application that I can't modify (I only have the binaries). This application connects to a web service and it seems like the connection is closed from the client side (my web app). I have increased the "executionTimeout" in the machine.config of the destination server but my web app seems to still stop after waiting for a while.
Is there a way to increase the timeout time for my web application by simply modifying the web.config? As I said... I can't modify the timeout in the code so my only option would be through config files.

I am experiencing a request timeout from IIS when I run a long operation. Behind the scene my ASP.NET application is processing data, but the number of records being processed is great, and thus the operation is taking a long time.
However, I think IIS times out the session. Is this a problem with IIS or ASP.NET session?

I have noticed that when I have a session that has expired, the Session_OnStart event fires with every new request.
I suppose that this behavior is not normal, because I was expecting that the session would re-start only with the first request and not with every subsequent request.
This behavior occurs only with sessions where the timeout period has been exceded.
The current conditions under which I have experienced this problem are:
I have experienced this problem with an application that is using the .NET 2.0 framework and with a session mode configured to InProc. This problem is happening both on Windows XP SP3 and Windows 2003 Server.

We have the timeout value set to 120 in our <form> tag within the web.config. We do not have a session timeout set.. and we have various connection strings.
We are having a problem where a session variable will disappear (become NULL) .. but, the form evidently remains 'open'.. or no re-login is required..... so, my question(s):
1. what is the relationship between form timeout and session timeout
2. how do I set session timeout

I'm looking for a good way to prevent the scenario of the page calling itself repeatedly.
I have a page, that to be rendered needs to make an HTTP request to an RSS feed. If the URL to that RSS feed happens to be the current page, it will fire off a request to itself. The new request would start off another request to the page, which would start another request... This continues until the site grinds to a halt when all available connections are busy in this recursive loop.
A few notes:
The URL to the RSS is entered by the user.
This is a page in a CMS, the URL of the page could be almost anything and could change after the RSS URL is entered.
In this case, the user entered a URL to a remote server that lead to a redirect back to the page.
A few ideas:
I could just deny all requests from the localhost IP before rendering.
Before sending the request, I could track in a common location which requests are active and not even send it if it's already in the middle of another request to the same address.
Maybe add a custom user-agent to the request header and deny the request if that user agent is seen?

I am using URL Routing in my .Net Web Application. I would like to prevent users from being able to access the .aspx page.
Example:
Actual URL - [URL]
Routed URL - [URL]
I want users to be able to access the page only by going to /Testimonials, but I would like to setup /Testimonials.aspx to redirect to its route at /Testimonials.
Is there an easy way to do this for Routed Pages throughout the application?

Hopefully I am posting this in the correct forum.
I am having a problem with my ASP.Net Web application. The application is developed using vb.net and is linked to a SQL Server database. Let me explain how the application works and the problem I am experiencing. The system is an online web app which allows registered users to create a CV online. One of the pages within the app gives users the chance to add a cover note to their CV. The page that allows them to do this consists of only a textarea control and a button control. The textarea allows users to input up to 4,000 characters.
Once the user clicks the 'Save' button to save their cover note info, the following code then executes.This code checks to see if the CV already has cover note info, if it does, then the application runs an update statement, otherwise, it runs an insert statement.The table within the database which records the cover note information is called tbl_covernote and has three columns, covernote_id (int and autoincrement), cv_id(int), covernote_text (nvarchar(max)).
The error which occurs sometimes is as follows:
Dim dr As SqlDataReader
Dim param(0) As SqlParameter
Finally [code]...

The session state timeout is set using this web.config element
<sessionState mode="InProc" cookieless="false" timeout="120" />
The forms auth is configured using this web.config element
<system.web>
<authentication mode="Forms">
<forms loginUrl="Login.aspx"
protection="All"
timeout="30"
name=".ASPXAUTH"
path="/"
requireSSL="false"
slidingExpiration="true"
defaultUrl="default.aspx"
cookieless="UseDeviceProfile"
enableCrossAppRedirects="false" />
</authentication>
</system.web>
What is the difference between the timeouts specified in each of these elements? If both are different, how would it work?

I have a page of each every click has ajax call to my server (hence, the ASP extends the session)
I have ASP.NET session set to Xmin. I want when X+1 min expires, I have expiration page. what I did was to set the JS timer to validate every x+1min to see if the session expired (the problem is that the JS and the ASP session timeouts are not synced)

I'm working with ASP.Net web services and am having a problem with a long-running process that takes about 5 minutes to complete, and it's timing out. To fix this, I was able to set the executionTimeout on the server's web.config to 10 minutes, and then set the .Timeout property on the Web Service object to approximately 9 minutes. Now, I'm worried that this may possibly cause some other web service calls to sit there for 10 minutes before they time out rather than the previous 90-100 seconds. I know the default on the client side is 100 seconds, but wasn't sure if updating the server's timeout setting would affect this.
Bottom line is - Is it safe to update the server's timeout setting to a long amount like 10 minutes, and rely on the default timeout on the client, or could this end up causing some problems?

We're trying to implement functionality that intercepts, inspects, and alters if needed data in the Request.QueryString and Request.Form collections.
Since Request.QueryString and Request.Form are readonly, is it possible to use a HttpModule to do this without Reflection or Response.Redirect?
We're thinking that we can construct a new HttpRequest, and replace the original one. Would there be any implications in doing this?
I know mocking this object is impossible without using HttpRequestWrapper, but wasn't sure whether ASP.NET sets other things beyond the constructor.

Is it at all possible to inject a request into IIS for a page, have IIS and ASP.Net handle it as normal, but get the response as html handed back to me programmatically?
Yes, I know that I could connect to port 80 using WebRequest and WebResponse, but that becomes difficult if you are accessing the IIS server from the same physical machine (loopback security controls et al).
Basically, I want to inject the request (eg for [URL]) between the points at which IIS would normally talk to the browser, and the point at which it would route it to the correct ASP.Net application, and get a response back from IIS between the points at which ASP.Net/IIS applies the httpfilters and hands the html back to the browser.
I'm predominantly working with IIS7 so if there is a solution that works just for IIS7 then thats not an issue.

This is a input
<input type="image" src="<%=Url.Content("~/images/shopping-cart.jpg")%>" alt="shopping cart" id="btnshoppingCart" name="btnshoppingCart" value="shoppingCart" />
when i browse the page with firefox and click on the input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is statisfied.
When i browse the same page with internet explorer 8 and click on the same input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is not satisfied. When i used the watch i saw that there is no key by the name of "btnshoppingCart" in either Request.Form or Request.Params if input is clicked from internet explorer. However when it is clicked from firefox there is value "shoppingCart" inside Request.Form and Request.Params against "btnshoppingCart" key. One more strange thing that i observed was that are two keys "btnshoppingCart.x" and "btnshoppingCart.y" inside both Request.Form and Request.Params whenver clicking is done from both internet explorer and firefox. This is happening against all inputs of type image irrespective if the input is present inside a html form or not. Forms are created like this
<% using (Html.BeginForm("Action", "Controller", FormMethod.Post)){%>
The version of internet explorer is 8.0 and firefox is 3.6.6
