title: What is the purpose of "Enable native XMLHTTP support" option in IE
body: <p>Our website uses AJAX call and uses <code>XMLHTTPRequest</code> to acheive that. When client uses an single IE instance through out the day and countinously navigating and refesing the page with in that IE, we end up with out of memory exception and forced to close the IE.</p>
  
  <p>By enabling the option <code>Enable native XMLHTTP support</code> in Advnaced tab of IE fixes the issue. Since we prefers native XMLHTTP object over ActiveXObject, the exception might be caused due to using ActiveXObject. But still not sure what could be the root cause or is there any other better way to solve the issue. We use IE8. We have never encounterd any such issue in other browsers(Firefox and chrome). Thanks</p>
