Hi! Sorry, for the delayed reply, I had an extremely busy week. 1. Your solution seems very elegant indeed, even though I was able to reconfigure OL to parse TMS layers as TileCache layers - and it works now, I'll give it a try. 2. Honestly, I wasn't really optimistic about this from the beginning, so that's not a surprise. 3. I've completely bypassed the proxy script and the different port number, using apache's mod_proxy, now POST works like a charm.
Thanks for your help!
