ASP .Net Output Caching and Ajax Control toolkit

Question

I'd like to know if there's a special way of implementing output caching and using a control from the ajax control toolkit. I keep getting a javascript error on a page with output caching and a tab control that says: ajaxtoolkit (my assembly prefix) is undefined.

This is the directive I added:

<%@ OutputCache Duration="3600" VaryByParam="none" %>

Answer 1

Microsoft does not support output caching in combination with ScriptControls, Extenders, or ScriptManagerProxies that need ScriptReferences. A workaround to the issue is to include the script references these resources require on the main script manager, outside the output cached control.

Answer 2

Since the output caching cannot be combined with the generated scripts by the AJAX framework yet (hopefully in a future version some similar behavior will be available crossing fingers), other type of optimization approach has to be made like replacing the ScriptManager for the ToolScriptManager.
