  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&#039;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
