pfSense

All present php scripts in pfSense call exit after sending a redir or finding an error or wanting to just finish processing.

This is not a desirable behaviour in FCGI case since calling exit shutdowns the php process and lighty is forced to re-spawn another php-fcgi process/instance.

This usually means lighty is doing a lot of work to keep php-working and also sometimes this is the issue with not being able to execute more than one request at a time.

The solution would be to s/exit/return/ but than the return value from require/include[_once] is needed to be checked.

This will help in performance and issues described above and probably the cause of some weird bugs fixed by hacks in the way.
