Thanks for the suggestion Scott. I've tried to add the current timestamp (via the javascript expression "new Date().getTime()" ) to the parameters and the query string (in all the combinations such as first adding it only to parameters, then only to query string, and then to both) and unfortunately, still no luck.
I did verify that in IE, the timestamp was being received by the servlet. One thing I did catch, however, is that the first time I tried it in firefox, firebug reported this exception: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIXMLHttpRequest.send This was thrown by the line this.transport.send() of prototype.js, but subsequent times, firefox did not produce this exception anymore (the ajax request did not raise any exceptions, yet still no luck in reaching the servlet) I looked this error code up on google and also tried looking it up on Mozilla's Source Code site (http://mxr.mozilla.org/mozilla1.8.0/source/ extensions/xmlextras/base/src/nsXMLHttpRequest.cpp#1423) and it looks like this NS_ERROR_FAILURE error is returned by the send() method in three places: Line 1429 (this is the case where more than one request is made with the same XMLHttpRequest object) Line 1553 (not quite sure how this one works) Line 1626 (right before firefox returns a successful response, it check whether mChannel exists, and if not, it returns this error).. my guess would be that this is the line that's causing my request not to work, but I can't figure out why. --Ronen On Mar 15, 10:15 am, Scott <counterstre...@gmail.com> wrote: > I have had similar issues before in my applications.
