Registration redirect to out of band URL as described in XEP-0077: In-Band Registration.
The already existing module
mod_register_redirect doesn’t add a stream feature advertising its capabilities and thus doesn’t work with clients like Conversations.
This module tries to take a simpler and more straight forward approach for admins who just want to redirect to an URL and do not need the features provided by
false and point
register_oob_url to the URL that handles your registration.
