<?php
// This module is currently !!!HIGHLY EXPERIMENTAL!!!
// You should think twice before running this on a production server
// as security mechanisms are not yet implemented and those that
// are implemented probably don't work.
// DAV mounts will probably fail if you don't use SSL, because some platforms refuse to send
// basic auth over non-encrypted connections.
// One could use digest auth - but then one has to calculate the A1 digest and store it for
// all acounts. We aren't doing that. We have a stored password already. We don't need another
// one. The login unfortunately is the channel nickname (webbie) as we have no way of passing
// the destination channel to DAV. You should be able to login with your account credentials
// and be directed to your default channel.
// This interface does not yet support Red stored files. Consider any content in your "store"
// directory to be throw-away until advised otherwise.
