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 large, 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?
Thanks in advance
This question is related to

Remove ~
character in location
so
path="~/Admin/SomePage.aspx"
becomes
path="Admin/SomePage.aspx"
Great and exhaustive answerby @Kev!
Since I did long processing only in one admin page in a WebForms application I used the code option. But to allow a temporary quick fix on production I used the config version in a <location>
tag in web.config. This way my admin/processing page got enough time, while pages for end users and such kept their old time out behaviour.
Below I gave the config for you Googlers needing the same quick fix. You should ofcourse use other values than my '4 hour' example, but DO note that the session timeOut
is in minutes, while the request executionTimeout
is in seconds!
And - since it's 2015 already - for a NON- quickfix you should use .Net 4.5's async/await now if at all possible, instead of the .NET 2.0's ASYNC page that was state of the art when KEV answered in 2010 :).
<configuration>
...
<compilation debug="false" ...>
... other stuff ..
<location path="~/Admin/SomePage.aspx">
<system.web>
<sessionState timeout="240" />
<httpRuntime executionTimeout="14400" />
</system.web>
</location>
...
</configuration>
I'm posting this here, because I've spent like 3 and 4 hours on it, and I've only found answers like those one above, that say do add the executionTime
, but it doesn't solve the problem in the case that you're using ASP .NET Core. For it, this would work:
At web.config file, add the requestTimeout
attribute at aspNetCore
node.
<system.webServer>
<aspNetCore requestTimeout="00:10:00" ... (other configs goes here) />
</system.webServer>
In this example, I'm setting the value for 10 minutes.
