I have been trying to set my web application session-timeout to 90 minutes without success.
In my web.config I have it set as follow:
<system.web>
<authentication mode="None" />
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
<sessionState mode="InProc" timeout="90"></sessionState>
</system.web>
... but the session keeps timing out at 20 minutes (default value).
Any insight on how to trace this problem?
