title: File Uploads Not Working When Deployed To Server
body: <p>I recently embarked on the endeavor of creating my own asynchronous file upload components for ASP.NET.  I took lessons learned form Darren Johnstone's FileUpload project and created an HttpModule for extracting the files from the submitted data.</p>
  
  <p>I got everything working as it should in testing with VS 2008 using the Development Server.  I even went so far during my testing to ensure that the request was being intercepted by the module before the files began uploading.  After I was satisfied with things, I deployed the project to our web server (Win 2008 w/ IIS 7).  I was horrified to learn that the controls were not functioning when deployed.</p>
  
  <p>After some remote debugging, I found that the HttpApplication.AuthenticateRequest event (my location for hooking in to the process) was not being invoked until the files were completely uploaded.</p>
  
  <p>I have checked everything that I can think of, and still have been unable to find a reason for this change in behavior.  Any ideas?</p>
