Author: Marius Zbihlei <[email protected]> Committer: Henning Westerholt <[email protected]> Date: Mon Oct 12 15:10:55 2009 +0300 If the user parameter is "<null>" (e.g a empty username in the request URI), do not copy this value to the rewritten uri. This is the case of a REGISTER request. Added statements that the parameters to the actually_rewrite func may not be null.
