WebResource.axd and ScriptResource.axd are
basically HTTP handlers in .NET Framework implementing IHttpHandler interface.
Purpose of these HTTP handlers is to get the embedded resources inside an
assembly.
We can easily find the following HttpHandler entry in root configuration file:
<add path="WebResource.axd" verb="GET" type="System.Web.Handlers.AssemblyResourceLoader"
validate="True"/>
WebResource.axd primarily focussing on embedded resources specifically web forms
and validations scripts while ScriptResource.axd is more focussed on those
scripts that have been registered with ScriptManager control.
ScriptResource has some additional features:
- Keeping different types of the same resource i.e. for debug and release.
- Compress scripts for transfering over HTTP.
- It can also be used for other frameworks
as jQuery.
