UrlRoutingHandler Class (System.Web.Routing)

.NET Framework Class Library

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.Routing (in System.Web.Routing.dll)

Syntax

Visual Basic (Declaration)

<AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level := AspNetHostingPermissionLevel.Minimal)> _
<AspNetHostingPermissionAttribute(SecurityAction.InheritanceDemand, Level := AspNetHostingPermissionLevel.Minimal)> _
Public MustInherit Class UrlRoutingHandler _
    Implements IHttpHandler

Visual Basic (Usage)

Dim instance As UrlRoutingHandler

[AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermissionAttribute(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)]
public abstract class UrlRoutingHandler : IHttpHandler

Visual C++

[AspNetHostingPermissionAttribute(SecurityAction::LinkDemand, Level = AspNetHostingPermissionLevel::Minimal)]
[AspNetHostingPermissionAttribute(SecurityAction::InheritanceDemand, Level = AspNetHostingPermissionLevel::Minimal)]
public ref class UrlRoutingHandler abstract : IHttpHandler

JScript

public abstract class UrlRoutingHandler implements IHttpHandler

Remarks

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>
