UrlRoutingHandler Class
Serves as base class for classes that enable you to customize how ASP.NET routing processes a request.
Namespace: System.Web.Routing
Assembly: System.Web (in System.Web.dll)
The UrlRoutingHandler type exposes the following members.
| Name | Description | |
|---|---|---|
 | IsReusable | Gets a value that indicates whether another request can use the UrlRoutingHandler instance. |
| RouteCollection | Gets or sets the collection of defined routes for the ASP.NET application. |
| 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(HttpContext) | Processes an HTTP request that matches a route. |
| ProcessRequest(HttpContextBase) | Processes an HTTP request that matches a route. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| VerifyAndProcessRequest | When overridden in a derived class, validates the HTTP handler and performs the steps that are required to process the request. |
| Name | Description | |
|---|---|---|
 | IHttpHandler.IsReusable | Gets a value that indicates whether another request can use the UrlRoutingHandler instance. |
| IHttpHandler.ProcessRequest | Processes an HTTP request that matches a route. |
You can customize how ASP.NET routing handles requests by mapping a file name extension to a particular routing handler instead of by using the UrlRoutingModule class as the routing handler for every request.
To customize how ASP.NET routing handles a request for a URL with a specific file name extension, you create a class that derives from the UrlRoutingHandler class. For example, you can create a customized routing handler that processes requests for a file that has the extension .abc.
To register a customized handler for a particular file name extension, you must add that handler in the Web.config file. The following example shows how to register a customized handler for an ASP.NET Web site that is running in IIS 6.0 or IIS 7.0 in Classic mode.
<system.web>
<httpHandlers>
<add verb="*" path="*.abc"
type="Contoso.Routing.CustomRoutingHandler" />
</httpHandlers>
</system.web>
The following example shows how to register the same handler for an ASP.NET Web site that is running in IIS 7.0.
<system.webServer>
<handlers>
<add verb="*" path="*.abc"
type="Contoso.Routing.CustomRoutingHandler"
resourceType="Unspecified" />
</handlers>
</system.webServer>
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
