BOSH is only specified using XML, nothing else. > *bosh sends xml payload encapsulates within http message body. BOSH sends nothing. BOSH is a protocol spec, not an actor.

What would you want to remove? What would be unwanted stanzas? What do you think is a stanza at all? > In the fourth reference it is said that "inclusion of tls negotiationw is > not allwed but not recommended" and in bosh protocol they are using > sasl authentication.In xmpp also we can use the sasl authentication.But by > default vysper use ssl. > So please make me clear about this. Eh..

No, I don't think you can add BOSH as an module. A suitable extension point would be AbstractSessionContext/SessionContext. Bernd
