Remark: Need to enable apache module mod_proxy and mox_proxy_http first.

Problem:
No protocol handler was valid for the URL. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.

Solution:
Enable Appache module mod_proxy and mod_proxy_http
