I am having problems trying to map an HttpHandler in the web.config.

This is the relevant config bit:

```
<httpHandlers>
  <add verb="*" path="*.hndlr" type="MyAssembly.MyHandler, MyAssembly" validate="false" />
</httpHandlers>

```

When I navigate to `http://localhost/myApp/whatever.hndlr` I am getting a server error 404 (not found).

It's the 1st time I am hooking up an HttpHandler so I might be missing something - any help appreciated!

**UPDATE**:

I managed to get it working using both answers so far - who's able to explain why it works gets the answer marked!

This is my config (won't work if you don't have both - I am running **IIS7 in classic mode**)

System.web:

```
<httpHandlers>
    <add verb="*" path="*MyHandler.hndlr" type="MyAssembly.MyAssemblyHandler, MyAssembly" validate="false"/>
</httpHandlers>

```

System.webserver:

```
<handlers>
    <add name="MyHandler" verb="*" path="*MyHandler.hndlr" type="MyAssembly.MyAssemblyHandler, MyAssembly" validate="false" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="Script"/>
</handlers>

```
