HttpModule not running with Visual Studio

I am using an HttpModule to do some URL shortening on my site. I am using Visual Studio 2008 and IIS 7, and .Net 3.5.

When the module is specified in the system.webServer element of web.config, and the site is run in IIS, it works fine. The config looks like this:

<system.webServer>
        <modules>
            <add name="MinimizeModule" type="ClipperHouse.UrlMinimizer.MinimizeModule" />
        </modules>...

My module attaches to the BeginRequest event, everything works. However, I can't get it to run using the built-in VS web server (Cassini). I tried moving the module config to the system.web element in web.config, no luck. I put a breakpoint on it, nothing happens.

Any thoughts on why this would be an issue?

(I also tried the Application_BeginRequest event in global.asax. Still no luck, though I'd prefer to keep everything in web.config anyway.)

Cassini, the development web server provided with IIS uses the IIS6 module syntax, so you must duplicate the module add like so

<system.web>
  <httpModules>
    <add name="MinimizeModule" type="ClipperHouse.UrlMinimizer.MinimizeModule" />
  </httpModules>
</system.web>


<system.webServer>
  <validation validateIntegratedModeConfiguration="false"/>
  <modules>
    <remove name="MinimizeModule" />
    <add name="MinimizeModule" type="ClipperHouse.UrlMinimizer.MinimizeModule" 
         preCondition="managedHandler" />
  </modules>
</system.webServer>

Note that I've also added a precondition to your IIS7 settings
