As per the documentation you quoted, and the
url you've included in your quote:
correct your php.ini from:
cgi.fix_pathinfo=1
to:
cgi.fix_pathinfo=0
or just comment it out all together, as:
;cgi.fix_pathinfo=1
If you have a recent version of PHP-FPM (~5.3.9+?), then you need to do nothing, as the safe behaviour below is already the default.
