From my own tests, it would appear that SSL prevents it from caching the XmlHttpRequest GET method. FWIW, IE behavior also changes depending on whether you are using SSL (https).

I find that a Last-modified date in the response is not enough to stop IE6 from caching, but adding an Expires response header persuades it to re-fetch the page.

The Browser should use the <code>If-Modified-Since</code> header by it self. I've researched <a href="http://www.mnot.net/cache_docs/">a bit more</a> and now explicitly use the <code>Expires</code> field. I have updated my post with the new results.

Also, related to document-write, one thing about script tag insertion is you can insert the script in the head or the body. Who knows if some browsers handle those differently.
