Scratch that...<location>
seems to work OK. Though, you need both the <web>
and <webServer>
entries to ensure that it works for both IIS and the Visual Studio Development Server. For example:
<location path="Files">`
<system.webServer>
<handlers>
<add name="MyHandler" path="*" verb="*" type="MyHttpHandler" />
</handlers>
</system.webServer>
<system.web>
<httpHandlers>
<add path="*" verb="*" type="MyHttpHandler" />
</httpHandlers>
</system.web>
</location>
