title: Call StaticFileHandler
body: <p>I have an HttpHandler mapped to aspnet_isapi.dll to perform a custom authentication check on static files (.pdf files) using IIS 7.5 in Classic mode:</p>
  
  <pre><code>void IHttpHandler.ProcessRequest(HttpContext context)
  {
    if(!User.IsMember) {
      Response.Redirect("~/Login.aspx?m=1");
     }
    else {
       //serve static content
     }
  }
  </code></pre>
  
  <p>The above code works fine, except for the else statement logic. In the else statement, I simply want to allow the StaticFileHandler to process the request, but I haven't been able to sort this out. Any suggestions on how to simply "hand off" the file back to IIS to serve the request as a normal StaticFile request, would be appreciated.</p>
