xmlhttprequest

XMLHttpRequest.js - Standard-compliant cross-browser XMLHttpRequest object implementation (Note: project moved to http://github.com/ilinsky/xmlhttprequest)

Important Notice: Project moved to http://github.com/ilinsky/xmlhttprequest

This project aims to:

  • Deliver unobtrusive standard-compliant (W3C) cross-browser implementation of the XMLHttpRequest 1.0 object
  • Fix ALL browsers quirks observed in their native XMLHttpRequest object implementations
  • Enable transparent logging of XMLHttpRequest object activity
