2877# This function returns a potentially modified version of SCRIPT_NAME

2880# user requests: /path/./to/script.cgi/x//y/z/../x?y, Apache will set:
2881# REQUEST_URI=/path/./to/script.cgi/x//y/z/../x?y
2882# SCRIPT_NAME=/path/to/env.cgi
2883# PATH_INFO=/x/y/x
2884#
2885# This is all fine except that some bogus CGI scripts expect
2886# PATH_INFO=/http://foo when the user requests
2887# http://xxx/script.cgi/http://foo
2888#
2889# Old versions of this module used to accomodate with those scripts, so
2890# this is why we do this here to keep those scripts backward compatible.
2891# Basically, we accomodate with those scripts but within limits, that is
2892# we only try to preserve the number of / that were provided by the user
2893# if $REQUEST_URI and "$SCRIPT_NAME$PATH_INFO" only differ by the number
2894# of consecutive /.
2895#
2896# So for instance, in: http://foo/x//y/script.cgi/a//b, we'll return a
2897# script_name of /x//y/script.cgi and a path_info of /a//b, but in:
2898# http://foo/./x//z/script.cgi/a/../b//c, we'll return the versions
2899# possibly sanitised by the HTTP server, so in the case of Apache 2:
2900# script_name == /foo/x/z/script.cgi and path_info == /b/c.
2901#
2902# Future versions of this module may no longer do that, so one should
