I am in exactly this boat as well. The way I get round it sometimes is to call a single “initialisation” code block for each new process that’s launched. It’s actually not as much overhead as it sounds and I used this approach heavily, for example, in a web server that was running 20 - 100 web processes that launched and died many times a second. So we could get round this just by moving your “On Server Startup” code to the “New Process” or “On Client Connection” event handlers. As long as it doesn’t have to run any queries it will be instant an un-detectable in terms of performance overhead. However thats just theory. I’m not even considering it at the moment because removing all the IP variables would be a daunting task. I’ll leave that for another lifetime ;) Peter ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
