FullWebService, are you using SS 2.4.2? I have the same infinite redirect problem if I follow the instructions by Banal in http://silverstripe.org/general-questions/show/251650?start=56#post289221
I think the _ss_environment.php handling might have changed since 2.4.1. Here's what i do to make it work:
1) create _ss_environment.php with
define('BASE_PATH', rtrim(dirname(dirname($_SERVER['SCRIPT_FILENAME'])), DIRECTORY_SEPARATOR));
2) Do NOT add require_once('conf/ConfigureFromEnv.php'); into mysite/_config.php
The rest of the symlinks creations are the same.
