Sometimes it's useful to have different interfaces to access XMPP.
This is example of sending message using HTTP POST to XMPP. For sure we need user auth information.
curl http://example.com:5280/msg/user -u email@example.com:mypassword -H "Content-Type: text/plain" -d "Server@host has just crashed!"
This would send a message to firstname.lastname@example.org from email@example.com
