title: How to pass "bin" as a GET parameter in WCF without receiving 404
body: <p>I have a .NET 4.0 WCF service that accepts GET requests.</p>
  
  <p>The URL to access it looks like 
  <a href="https://api.mysite.com/MyService.svc/FunctionName/Param1/Param2/Param3" rel="nofollow">https://api.mysite.com/MyService.svc/FunctionName/Param1/Param2/Param3</a></p>
  
  <p>When Param3 is the word "bin" I get a 404</p>
  
  <p>This is strange because if the WCF is malformed it shows me a "Endpoint not found" error</p>
  
  <p>I realized it only did this when passing in "bin" as any of the params</p>
  
  <p>How can I accept this word without it first looking for a physical path and replying with a 404 ?</p>
