Scope of implementation

  1. Deliver unobtrusive standard-compliant cross-browser implementation of the XMLHttpRequest 1.0
  2. Fix browsers quirks observed in their native XMLHttpRequest object implementations
  3. Enable transparent sniffing of XMLHttpRequest object activity

How To Use

    <!-- ... -->
    <script type="text/javascript" src="XMLHttpRequest.js"></script>
    <!-- ... -->

XMLHttpRequest 2 features

The library does not and will not add support for any features found in XMLHttpRequest 2 since it is not possible to provide complete fallback implementation in older Internet Explorer browser for which this library was primarily developed. If you use this library, I recommend starting adding conditional HTML comments to limit exposure of the library only to browsers where it is really needed.

    <!--[if lte IE 9]>
    <script type="text/javascript" src="XMLHttpRequest.js"></script>
