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.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The ScriptResourceHandler type exposes the following members.
| Name | Description | |
|---|---|---|
|
ScriptResourceHandler | Initializes a new instance of the ScriptResourceHandler class. |
| Name | Description | |
|---|---|---|
|
IsReusable | When overridden in a derived class, gets a value that indicates whether another request can use the instance of the class. |
| Name | Description | |
|---|---|---|
|
|
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
|
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
|
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
ProcessRequest | When overridden in a derived class, processes HTTP Web requests for a script file that is embedded as a resource in an assembly. |
|
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
|
IHttpHandler.IsReusable | Gets a value that indicates whether another request can use the IHttpHandler instance. |
|
IHttpHandler.ProcessRequest | Processes HTTP Web requests for a script file that is embedded as a resource in an assembly. |
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.
Note

|
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>
