initializes request_info structure
specifically in this section we handle proper translations
for:
PATH_INFO
derived from the portion of the URI path following
the script name but preceding any query data
may be empty
PATH_TRANSLATED
derived by taking any path-info component of the
request URI and performing any virtual-to-physical
translation appropriate to map it onto the server's
document repository structure
empty if PATH_INFO is empty
The env var PATH_TRANSLATED **IS DIFFERENT** than the
request_info.path_translated variable, the latter should
match SCRIPT_FILENAME instead.
SCRIPT_NAME
set to a URL path that could identify the CGI script
rather than the interpreter. PHP_SELF is set to this
REQUEST_URI
uri section following the domain:port part of a URI
SCRIPT_FILENAME
The virtual-to-physical translation of SCRIPT_NAME (as per
PATH_TRANSLATED)
These settings are documented at
http://cgi-spec.golux.com/
Based on the following URL request:
http://localhost/info.php/test?a=b
should produce, which btw is the same as if
we were running under mod_cgi on apache (ie. not
using ScriptAlias directives):
PATH_INFO=/test
PATH_TRANSLATED=/docroot/test
SCRIPT_NAME=/info.php
REQUEST_URI=/info.php/test?a=b
SCRIPT_FILENAME=/docroot/info.php
QUERY_STRING=a=b
but what we get is (cgi/mod_fastcgi under apache):
PATH_INFO=/info.php/test
PATH_TRANSLATED=/docroot/info.php/test
SCRIPT_NAME=/php/php-cgi (from the Action setting I suppose)
REQUEST_URI=/info.php/test?a=b
