I have added a CombineScriptsHandler in web.config and added a ToolkitScriptManager with the propertier ScriptMode="Release" CombineScripts="true".
I could see that its combining the scripts to one file CombineScriptsHandler.axd in the response, but for somereason, its not getting cached in the browser (with a 304 Not Modified), instead it issues a seperate request on every refresh and ends up with 200 OK response).
As per Stephen Walther's detailed documentation here , the combinedscript file is supposed to be cached - but unfortunately its not working for me.
Is there any additional steps I am missing here to have this combined script file cached? Please advice.
