Using Apache2-module proxy_balancer as fallback solution for the backend
My servers are mostly work with a normal load, but sometimes they have stress. In some cases the content application like TYPO3 or TomCat could not handle the mass of requests. So I've been searched for a automatic solution to display a busy-Page. The Apache-Modul mod_proxy_balancer provides a solution for me. It doesn't matter if the content is on the same machine or hosted on dedicated server(s) in the background. The difference is only the source loopback or some foreign IP addresses.
This modules should be loaded: proxy proxy_balancer proxy_http and if you use SSL to the backend proxy_connect.
