This is not a typical xml-dev thread, unless someone wants to wax philosophical about the impact of AJAX on debugging. You didn't say what the fault symptoms were, but I guess from your "Heavy server load..." message that nothing is downloaded at all. You don't say if there is a continuous busy-download status. You wrote "but later it will fail." Is there a substantial time lapse over the course of your testing that may incur a session timeout? How long is after you start is "later" for your testing? Are you logged in as a member? Does the site use a dummy session for those browsing without an account? Off the top of my head... things that appear erratic during testing... - a race condition in the client or a wrong value in a Javascript variable, due to an asynchronous setTimeout() or XMLHttpRequest callback - server-side race conditions in database handling code - a server-side global that is not being set consistently - sessions that are timing out, or which are stored in a temp directory that is being wiped periodically - Mitch Amiano Tri-XML 2006 Conference http://www.trixml.org/confschedule.shtml - July 27-29, 2006 - Beautiful, warm Raleigh, NC USA - $450 regular rate for 3 day conference on XML Scott Abel wrote: > Hello fellow XML Pros... > > Just curious if anyone has any experience debugging AJAX application > problems.
