Answer 1

You might need to register the handler... Is it in you web.config for IIS7?

try looking at this link?

<add path="*.ashx" verb="*" type="System.Web.UI.SimpleHandlerFactory" validate="True" />

IIS7 file mappings - .asax, .ashx, .asap

Here's a quick edit to web.config for caching images/css/js in .NET

<staticContent>
 <clientCache httpExpires="Sun, 29 Mar 2020 00:00:00 GMT" cacheControlMode="UseExpires" />
</staticContent>
