Summary<br>
-------------<br>

Clicking the link does an ajax post. There is no visible response in the test case, but there should be no javascript error either.
All this works fine in firefox.<br><br>

In internet explorer 7 and 8, and jquery 1.4.2, the post will fail with a jQuery exception.<br>
The exception occurs when it tries to create an XMLHTTPObject.<br><br>

Usually if you force a reload of the page, by holding SHIFT+refresh, oddly, the link will then work. <br><br>

Then go to the address bar, and hit enter so its basically using a cached copy, and the link will fail again.<br><br>

This is an odd problem, and I dont know how to describe it, but the reload issue is not actually cache related that I can tell. Disabling the browser cache completely produces the same results.<br><br>

Reverting to jquery 1.2.6 resolves the problem (although there might be later versions which work too) <br><br>
