I ran into an interesting issue using the jQuery UI tabs ajax style and Internet Explorer. 

If you setup the tabs with the with the cache turned off, they will still be cached in IE.   I had worked around this issue by adding a counter that changed every time to my href for the tab, but I found a more elegant solution and thought I would share.

 $(document).ready(function(){

$("#tabs").tabs({ 

spinner: 'Loading...',

cache: false

});

});

The solution for this is to not only set the cache to false, but also to use the ajax options and set cache to false there also.  So the code would change to this...

 $(document).ready(function(){

$("#tabs").tabs({

spinner: 'Loading...',

cache: false,

ajaxOptions: {cache: false}

});

});
