title: How to get IIS 7 to route requests for .css files to aspnet_isapi.dll?
body: <p>We currently use <a href="http://www.dotlesscss.org/" rel="nofollow">DotLess</a> on an ASP.NET web application hosted on IIS 6. In order to get this to work, we needed to tweak our IIS settings so that requests for *.css files would get handled by aspnet_isapi.dll (right click on website in IIS -> properties -> home directory tab -> configuration).</p>
  
  <p>We're now moving this web application over to IIS 7 (classic mode) and can't seem to find a way to set up IIS 7 in this manner. Is there a way to change IIS 7's settings so that requests for *.css files get handled by aspnet_isapi.dll like we were doing in IIS 6?</p>
