Timeout expired

[Scorpion657]

Hey I really need help.

I have a Website coded using ASP.NET and VB and for some reason, i'm getting the following error when I try to upload or access a large file which is stored in the database. It was working fine when I was runing the site on the localhost. I added the following line to the web.config file to increase the timeout:

<httpRuntime 
maxRequestLength="1048576"
executionTimeout="3600"/>

I also added:

connection timeout = 60

in the Sql Connection string but still nothing

Here is the error:

Server Error in '/' Application.

I would really appreciate any help I can get. Thanks a lot

The timeout in the connectionstring ONLY dictates the timeout for trying to connect to the server.
I am unsure where the query timeout is kept. Possibly only in the management of the SQL server somewhere.
