958   specificly in this section we handle proper translations
959   for:
960 
961   PATH_INFO
962 	derived from the portion of the URI path following
963 	the script name but preceding any query data
964 	may be empty
965 
966   PATH_TRANSLATED
967     derived by taking any path-info component of the
968 	request URI and performing any virtual-to-physical
969 	translation appropriate to map it onto the server's
970 	document repository structure
971 
972 	empty if PATH_INFO is empty
973 
974 	The env var PATH_TRANSLATED **IS DIFFERENT** than the
975 	request_info.path_translated variable, the latter should
976 	match SCRIPT_FILENAME instead.
977 
978   SCRIPT_NAME
979     set to a URL path that could identify the CGI script
980 	rather than the interpreter.  PHP_SELF is set to this
981 
982   REQUEST_URI
983     uri section following the domain:port part of a URI
984 
985   SCRIPT_FILENAME
986     The virtual-to-physical translation of SCRIPT_NAME (as per
987 	PATH_TRANSLATED)
988 
989   These settings are documented at
990   http://cgi-spec.golux.com/
991 
992 
993   Based on the following URL request:
994 
995   http://localhost/info.php/test?a=b
996 
997   should produce, which btw is the same as if
998   we were running under mod_cgi on apache (ie. not
999   using ScriptAlias directives):
1000 
1001   PATH_INFO=/test
1002   PATH_TRANSLATED=/docroot/test
1003   SCRIPT_NAME=/info.php
1004   REQUEST_URI=/info.php/test?a=b
1005   SCRIPT_FILENAME=/docroot/info.php
1006   QUERY_STRING=a=b
1007 
1008   but what we get is (cgi/mod_fastcgi under apache):
1009 
1010   PATH_INFO=/info.php/test
1011   PATH_TRANSLATED=/docroot/info.php/test
1012   SCRIPT_NAME=/php/php-cgi  (from the Action setting I suppose)
1013   REQUEST_URI=/info.php/test?a=b
