[jQuery] Double submitted ajax requests

[Josh Ain]

Very intermittently, I am finding ajax requests submitted with jquery are
being submitted twice, once with parameters, and once without parameters.
The code looks something like this:

jQuery.post("url?id=id",
                {param1: param1,
                  param2: param2,
                  id: id},
                  callback);

We are using jquery 1.3.1, and the error occurred most recently from a
firefox 2 browser.

What we see on the server side, is a request with all the expected
parameters, then about 200ms later, a request with only the id parameter.
Does anybody have any idea why this is happening, and how to avoid this
issue?

Thank you for any assistance!
