// 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.
