I've got an IIS 6.0 server that won't serve pages over SSL to some browsers. In Webkit-based browsers on OS X 10.6, I can't load pages at all. In MSIE 8 on Windows XP SP3, I can load pages, but it will sometimes hang downloading images or sending POSTs.
Working: Firefox 3.6 (OS X + Windows) Chrome (Windows)
Partially Working: MSIE 8 (works sometimes, but hangs up, especially on POSTs)
Not Working: Chrome 5 (OS X) Safari 5 (OS X) Mobile Safari (iOS 4)
On OS X (the easiest platform for me to test on), Chrome and Firefox both negotiate the same TLS Cipher, but Chrome hangs on or after the post-negotiation handshake.
Chrome packet capture (via ssldump):

Update: Here's a Wireshark capture from the server end. What's going on with those two much-delayed RST packets? Is that just IIS terminating what it perceives as a non-responsive connection?
