/**
* Returns whether generated URLs should be formatted using PATH_INFO, taking the
* [usePathInfo](http://craftcms.com/docs/config-settings#usePathInfo) config setting value into account.
*
* This method will usually only be called in the event that {@link omitScriptNameInUrls()} returns `false`
* (so “index.php” _should_ be included), and it determines what follows “index.php” in the URL.
*
* If it returns `true`, a forward slash will be used, making “index.php” look like just another segment of the URL
* (e.g. http://example.com/index.php/some/path). Otherwise the Craft path will be included in the URL as a query
* string param named ‘p’ (e.g. http://example.com/index.php?p=some/path).
*
* If the usePathInfo config setting is set to `true` or `false`, then its value will be returned directly.
* Otherwise, `usePathInfo()` will try to determine whether the server is set up to support PATH_INFO.
* (See http://craftcms.com/help/enable-path-info for instructions.)
*
* It does that by creating a dummy request to the site URL with the URI “/index.php/testPathInfo”. If the server
* supports it, that request should be sent to Craft’s index.php file, which will detect that this is an
* PATH_INFO-testing request, and simply return “success”. If anything besides “success” is returned
* (i.e. an Apache-styled 404 error), then Craft assumes the server is not set up to support PATH_INFO.
*
* Results of the PATH_INFO test request will be cached for the amount of time specified by the
* [cacheDuration](http://craftcms.com/docs/config-settings#cacheDuration) config setting.
*
* @return bool Whether generaletd URLs should be formatted using PATH_INFO.
