Hi All --

If you use XMLHtppRequest (with MSXML) you may meet with a nasty caching issue.
Description and solution is here: http://www.subbu.org/blog/2005/10/xmlhttprequest-and-caching - the solution from Marco Dorantes worked well for me:

request.setRequestHeader(“If-Modified-Since”, “Sat, 1 Jan 2000 00:00:00 GMT”);

The other ones proposed in the referred above article and comments didn't.
I do use Win7 and IE 9.0.8112.16421

Thank you.
