1100 The env var PATH_TRANSLATED **IS DIFFERENT** than the
1101 request_info.path_translated variable, the latter should
1102 match SCRIPT_FILENAME instead.
1103
1104 SCRIPT_NAME
1105 set to a URL path that could identify the CGI script
1106 rather than the interpreter. PHP_SELF is set to this
1107
1108 REQUEST_URI
1109 uri section following the domain:port part of a URI
1110
1111 SCRIPT_FILENAME
1112 The virtual-to-physical translation of SCRIPT_NAME (as per
1113 PATH_TRANSLATED)
1114
1115 These settings are documented at
1116 http://cgi-spec.golux.com/
1117
1118
1119 Based on the following URL request:
1120
1121 http://localhost/info.php/test?a=b
1122
1123 should produce, which btw is the same as if
1124 we were running under mod_cgi on apache (ie. not
1125 using ScriptAlias directives):
1126
1127 PATH_INFO=/test
1128 PATH_TRANSLATED=/docroot/test
1129 SCRIPT_NAME=/info.php
1130 REQUEST_URI=/info.php/test?a=b
1131 SCRIPT_FILENAME=/docroot/info.php
1132 QUERY_STRING=a=b
1133
1134 but what we get is (cgi/mod_fastcgi under apache):
1135
1136 PATH_INFO=/info.php/test
1137 PATH_TRANSLATED=/docroot/info.php/test
1138 SCRIPT_NAME=/php/php-cgi (from the Action setting I suppose)
1139 REQUEST_URI=/info.php/test?a=b
1140 SCRIPT_FILENAME=/path/to/php/bin/php-cgi (Action setting translated)
1141 QUERY_STRING=a=b
1142
