I am having a website (developed in ASP.NET 2.0 (C#)) registered with godaddy.com But when I am adding HttpModule in my web.config as follow: 

<httpModules>
  <add type="WwwSubDomainModule" name="WwwSubDomainModule" />
</httpModules>

but it gives me "500 Internal Server Error". When I removed the above tag then my website is working fine. Can anyone guess why its creating this problem??

Got it guys :)

I was facing this problem since last October 2008, but finally I got this why? Instead of adding modules like I have added above in my question, use the following new module syntax made for IIS7 (godaddy is using IIS7 for windows hosting)

<configuration>
   <system.webServer>
      <modules>
         <add name="Header" type="Contoso.ShoppingCart.Header"/>
      </modules>
   </system.webServer>
</configuration>

Place all your modules under here and you're done! It's nice and works perfect!

And "@Jon Skeet" there is no need to have namespace for modules, even without namespace you can get it work!

Do read more about this tag here http://www.iis.net/ConfigReference/system.webServer/modules
