title: HTTP 405 on Error on HTTP POST IIS ASP .NET
body: <p>I'm working on a web application that is referenced from another, external application. The external application tries to do a <code>POST</code> on the <code>vdir</code> when opening. At this point, I get an HTTP 405 Error:</p>
  
  <blockquote>
    <p>HTTP Error 405 - The HTTP verb used to access this page is not allowed.
    Internet Information Services (IIS)</p>
  </blockquote>
  
  <p>I checked the IIS event logs and I see that the external application tries to post, but I can't change permissions for a directory, since I need an extension.</p>
  
  <p>Any ideas?</p>
