title: No 'Access-Control-Allow-Origin' header - Same Domain?
body: <p>Today I attempted to browse a new feature recently deployed to our testing environment (NOT LOCAL).  After navigating to the new feature I was met with a blank page.  Confused, I checked Chrome's console and found an error:</p>
  
  <pre><code>XMLHttpRequest cannot load https://test.mytestsite.com/SomeApplication/api/SomeController/SomeMethod/8?Id=523283&amp;SecondId=1612w3426653. 
  No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://test.mytestsite.com' is therefore not allowed access.
  </code></pre>
  
  <p>This code makes an ajax call to a WebAPI (on the same domain) to retrieve some information on <code>document.Ready</code>.  I understand the error and I'm familiar with it's typical cause.  However, this call is being made from <em>within the same domain AND it works for the other developers on my team</em>.</p>
  
  <p><strong>Symptoms:</strong>
  - Does not work for IE or Chrome/Incognito
  - Does work for FireFox
  - Works on all browsers for at least 4 other developers on the same domain that I reside on. (Indicating to me that this is an environmental issue)</p>
  
  <p><strong>Possible causes:</strong>
  - I was doing some CORS research several weeks ago and perhaps I configured some Windows 7 setting to cause this to happen?</p>
  
  <p>Google is saturated with the standard CORS issues, so I'm asking here and hopefully someone can help.</p>
