Hey Guys
I'm sorry to bother, but I have the same problem, and I've been trying
to get around it.
I added the option 'cache:false' on the tabs script:
$(function() {
 $('#ajaxtab').tabs({
    remote: true,
    cache: false
  });
})
But it did not work...
I also tryed to add:
$.ajaxSetup({
  global: false,
  cache:false
});
Also nothing...
On my ajaxRequest I'm using POST as method:
sendRequest: function (postVars, url) {
        request.open("POST", "ajaxcomments/insert.php", true);
                request.onreadystatechange = ajaxRequest.response;
                request.setRequestHeader("Content-Type", "application/x-www-form-
urlencoded");
                request.send(postVars);
    }
Please can you help me out?! I'm really desparate now. I mean
unfortunatelly most users use IE and I have to make it work :S

Thanks in Advance.
