1) the “/path/to/your/documentroot” is effectively the path used to find the php script then run it. but substituting %{DOCUMENT_ROOT} does not work. Is there a means of making this happen?
2) with multiple vhosts I would need a separate proxypassmatch line for each vhost. If I do not need to change the php user, is there any need to use a different port number such as fcgi://127.0.0.1:9001, or is it ok to use the same ip/port combo with a different /path/to/your/documentroot?
3) Are there any other parameters passed to the proxy port?
