Make PATH_INFO work with CGI environments
Some environments with CGI add a given PATH_INFO
directly to the server variable PATH_TRANSLATED. Currently
TYPO3 does not use PATH_INFO, but mixed setups with
other frameworks on some FastCGI environments do not
Example - Call: "/mysite/index.php/my/path/info"
/my/path/info is the last part after the actual script file.
Some environments add this to the PATH_TRANSLATED
variable, but it needs to be stripped away.
