The problem comes at tidying up time. Apache provides no method of performing operations when the server shuts down. This is especially relevant with things like open database connections and is probably why the original poster was talking about XML-RPC. A workable solution is to open your database connections in a separate process to Apache/mod_python and connect via a local socket or with something like XML-RPC or with http://sourceforge.net/projects/sqlrelay Cheers, Richard -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Richard Lewis Sonic Arts Research Archive http://www.sara.uea.ac.uk/ JID: ironchicken at jabber.earth.li -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
