Title: Bug 1101836: Apache shouldn't disable backend when it can't connect to it

apache with vhost plugin disables a backend for a minute when it can't connect to it --

[Wed May 28 17:00:35 2014] [error] (111)Connection refused: proxy: HTTP: attempt to connect to 127.1.244.129:8080 (127.1.244.129) failed
[Wed May 28 17:00:35 2014] [error] ap_proxy_connect_backend disabling worker for (127.1.244.129)
[Wed May 28 17:00:35 2014] [error] proxy: HTTP: disabled connection for (127.1.244.129)

This fix prevents apache from doing that.
