How do I use my HTTP handlers for selected paths and MVC handler for the rest?

Question

I have an MVC2 application. I also have a set of ready HTTP handlers that derive from System.Web.IHttpHandler. How do I use them together?

I tried the following in web.config:

<system.webServer>
    <!--other stuff-->
        <handlers>
            <add name="MyCustomHandler" verb="GET" path="MySpecificPath*" type="CustomHandling.CustomHttpHandlerBase, CustomHAndlingAssembly"/>
            <add name="MvcHttpHandler" preCondition="integratedMode" verb="*" path="*.mvc" type="System.Web.Mvc.MvcHttpHandler, System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"/>
        </handlers>
</system.webServer>

yet control never reaches my handler and MVC handler is used for all requests.

How do I use my handler for one specific path and MVC handler for all other paths?

Answer 1

I believe that you need to ignore those specific paths from routes collection in application start. For example,

routes.IgnoreRoute("MySpecificPath/{*pathInfo}");

Otherwise UrlRoutingModule will match with the route and then http handler will be located via IRouteHandler for that route.
