-# WE USE THIS TO COMPENSATE FOR A BUG IN APACHE 2 PRESENT AT LEAST UP THROUGH 2.0.54
+# This function returns a potentially modified version of SCRIPT_NAME
+# and PATH_INFO. Some HTTP servers do sanitise the paths in those
+# variables. It is the case of at least Apache 2. If for instance the
+# user requests: /path/./to/script.cgi/x//y/z/../x?y, Apache will set:
+# REQUEST_URI=/path/./to/script.cgi/x//y/z/../x?y
+# SCRIPT_NAME=/path/to/env.cgi
+# PATH_INFO=/x/y/x
+#
+# This is all fine except that some bogus CGI scripts expect
+# PATH_INFO=/http://foo when the user requests
+# http://xxx/script.cgi/http://foo
+#
+# Old versions of this module used to accomodate with those scripts, so
+# this is why we do this here to keep those scripts backward compatible.
+# Basically, we accomodate with those scripts but within limits, that is
+# we only try to preserve the number of / that were provided by the user
+# if $REQUEST_URI and "$SCRIPT_NAME$PATH_INFO" only differ by the number
+# of consecutive /.
+#
+# So for instance, in: http://foo/x//y/script.cgi/a//b, we'll return a
+# script_name of /x//y/script.cgi and a path_info of /a//b, but in:
+# http://foo/./x//z/script.cgi/a/../b//c, we'll return the versions
+# possibly sanitised by the HTTP server, so in the case of Apache 2:
+# script_name == /foo/x/z/script.cgi and path_info == /b/c.
+#
+# Future versions of this module may no longer do that, so one should
+# avoid relying on the browser, proxy, server, and CGI.pm preserving the
+# number of consecutive slashes as no guarantee can be made there.
