title: WebResource.axd requested without parameters - This is an invalid webresource request
body: <p>I'm finding this problem every now and then in my production website, and it has me absolutely stumped...</p>
  
  <p>My app works perfectly in both dev and production, but every now and then, I get an e-mail from my global error handling with this:</p>
  
  <p>MESSAGE: This is an invalid webresource request.<br>
  URL: /WebResource.axd<br>
  (which means that for some reason webresource.axd was requested without specifying any GET parameters)</p>
  
  <p>I'm not doing anything with webresource.axd myself, I don't get any of my resources through it, it's only used automatically by .Net to serve it's typical JS for validators, etc.</p>
  
  <p>Any idea why this might be getting requested without parameters?
  Has anyone encountered this?</p>
