// XMLHTTP JS class is is developed by Alex Serebryakov (#0.9.1)
// For more information, consult www.ajaxextended.com

// What's new in 0.9.1:
// - fixed the _createQuery function (used to force multipart requests)
// - fixed the getResponseHeader function (incorrect search)
// - fixed the _parseXML function (bug in the ActiveX parsing section)
// - fixed the _destroyScripts function (DOM errors reported)
