Answer 1

I think this is a bug in mod_proxy_fcgi, connected to an issue resolved in Apache 2.4.12 onwards:

mod_proxy_fcgi: Remove proxy:balancer:// prefix from SCRIPT_FILENAME passed to fastcgi backends. [Eric Covener]

Here is a link

Unfortunatelly it was not good enough as Apache is sending the SCRIPT_FILENAME with a starting slash, similar to \c:\fileName.php, which is not resolved as a local file name and is never executed. You may verify this using a network sniffer(Wireshark) listening on your FastCGI port.

I will be more than happy to see this issue resolved officially since I am not confident in recompiling Apache by myself and so I am using distributions from apachelounge.
