Operation has timed out in ASP.Net Application

[Guest]

Hello,

I'm developing a web appliation in ASP.Net. My web appliation
communicates with Web Services for several operations. Everything is working
fine except one operation.

Web application uploads a file and send it to web service in the form of
Bytes by calling its function. Web Service do some operations on that file,
which may take several minutes to let Web Application to wait. But after 90
seconds, my Web Application throughs an exception that the "Operation has
timed out".

I tried to change the timeout parameters in web.config file like...

<httpRuntime
executionTimeout="1000"
maxRequestLength="409600"
useFullyQualifiedRedirectUrl="false"
/>

also doing this

<sessionState
mode="InProc"
stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"
cookieless="false"
timeout="1000"
stateNetworkTimeout = "1000"
/>

But these things are not controlling that TimeOut Exception. I also tried to
change the TimeOut Parameters from IIS but non prevail.

Are there any other parameters in web.config file for controlling this
Exception? or I will have to do something else.
