load balancing

I've put together some primitive load balancing for the manual-lookup feature of www.php.net. It works like this: If there is a mirror in your country that has the search feature enabled, the search is redirected to that mirror. Otherwise, if the load is not too high, serve the search on the www.php.net box itself. If the load is too high, we serve a 503 response with a suggestion to try again later, or use a mirror. We are currently tuning this "too busy" threshold, as well as examining areas of the phpweb (and looking at log files) to determine where we can make additional optimizations. If you are running an official mirror and are not currently running the local search feature, it would be nice if you could enable it so that we can improve the load balancing, particularly if the physical location of your mirror is in a large country, or if no other mirrors in your country support it. --Wez.
