Serves as base class for classes that enable you to customize how ASP.NET routing processes a request.
Assembly: System.Web.Routing (in System.Web.Routing.dll)
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 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>
