XMLHttpRequest Problem

I am writing a single web application using XUL. In this Iam using the AJAX XMLHttpRequest object to send a request to the server. When I use a GPRS connection to send a request to the server from my web application, the request is not executed, but readyState has changed to 4 and status = 0. If the request does not exit, how does the ReadyState parameter change.

The same code works fine on the local network. If I send a request to the server from the browser using GPRS, it works fine. Can any body help me in solving this problem.

Thanks at Advance.

request not coming

How do you define this?

Are you using an HTTP scheme? If so, the status == 0 is a problem ( Google says there are known quirks in Firefox).

status == 0 is also returned when the request uses a protocol other than HTTP. Therefore, if you make a file: // request randomly, this explains all the symptoms ...

[edit 2009-09-07] This problem was also found: https://bugzilla.mozilla.org/show_bug.cgi?id=488605 aborted XMLHttpRequests has the status == 0, since Firefox 3.

[edit] I'm not sure / sure, but I think that cross-domain requests that are not allowed also end with status == 0.
