Perhaps this doesn't apply, but I think it should be mentioned none the less. The default CommandTimeOut is 30 seconds. This should be plenty of time for any actions that are happening in 99.9% of a web application. Unless you are absolutely sure that the action should take longer than that, you should spend your time trying to optimize the sql so that it returns in <30 seconds. Proper indexing is a good place to start for that.
