1100 REQUEST_URI
1101 uri section following the domain:port part of a URI
1102
1103 SCRIPT_FILENAME
1104 The virtual-to-physical translation of SCRIPT_NAME (as per
1105 PATH_TRANSLATED)
1106
1107 These settings are documented at
1108 http://cgi-spec.golux.com/
1109
1110
1111 Based on the following URL request:
1112
1113 http://localhost/info.php/test?a=b
1114
1115 should produce, which btw is the same as if
1116 we were running under mod_cgi on apache (ie. not
1117 using ScriptAlias directives):
1118
1119 PATH_INFO=/test
1120 PATH_TRANSLATED=/docroot/test
1121 SCRIPT_NAME=/info.php
1122 REQUEST_URI=/info.php/test?a=b
1123 SCRIPT_FILENAME=/docroot/info.php
1124 QUERY_STRING=a=b
1125
1126 but what we get is (cgi/mod_fastcgi under apache):
1127
1128 PATH_INFO=/info.php/test
1129 PATH_TRANSLATED=/docroot/info.php/test
1130 SCRIPT_NAME=/php/php-cgi (from the Action setting I suppose)
1131 REQUEST_URI=/info.php/test?a=b
1132 SCRIPT_FILENAME=/path/to/php/bin/php-cgi (Action setting translated)
1133 QUERY_STRING=a=b
1134
