ScriptResourceHandler Class

Provides an HTTP handler for processing requests for script files that are embedded as resources in an assembly. This class cannot be inherited.

Namespace:  System.Web.Handlers
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

public class ScriptResourceHandler implements IHttpHandler

The ScriptResourceHandler class processes all requests for embedded script files that are referenced through the ScriptManager class. The ScriptResourceHandler object retrieves the embedded script library and any localized resources for the script library. If the NotifyScriptLoaded property is set to true, the ScriptResourceHandler object adds a call at the end of the script file to the notifyScriptLoaded method of the Sys.Application object.

By default, the ScriptResourceHandler class compresses and caches embedded script files for Internet Explorer 7. You can turn compression and caching off through the EnableCompression and EnableCaching properties of the ScriptingScriptResourceHandlerSection class. You set these properties in the Web.config file.

NoteNote:

You can turn compression on for earlier versions of Internet Explorer by creating an alias for Internet Explorer 7 in the clientTarget section of the Web.config file. You then programmatically set the value of the ClientTarget property to that alias. However, we do not recommend this approach because it will cause a decrease in performance and it introduces a high risk of errors.

The default Web.config file for AJAX-enabled ASP.NET Web applications adds the ScriptResourceHandler as a handler. You can manually add the handler to your application by including the following element in the Web.config file:

<httpHandlers>
  <add verb="GET,HEAD" path="ScriptResource.axd" 
    type="System.Web.Handlers.ScriptResourceHandler, 
    System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, 
    PublicKeyToken=31bf3856ad364e35" validate="false" />
</httpHandlers>
