title: IIS 7 query string length
body: <p>I`m using Asp Net Mvc 4 Web Api and I need to make request with querystring length > 2000 symbols</p>
  
  <p>I`ve allready set maxQueryStringLength="10000" parameter in web.config.
  Everything works well on my developer machine
  On IIS it works only if querystring &lt; 2000 symbols,
  but if querystring > 2000 symbols I get an error: 404 Not Found</p>
  
  <p>Any considerations?</p>
