Both require a bridge between HTTP and XMPP.ġ. However, if you want to address the problem with XMPP bound to HTTP, for example, because Javascript can send HTTP requests, there are two possible solutions. This problem does not exist in the original XMPP Core specification ( RFC 6120), where XMPP is bound to TCP. The server’s inability to push data makes it unnatural to implement XMPP over HTTP.

Only the client sends requests, and the server can only respond. The second difficulty is the unidirectional behavior of HTTP. However, this problem can be addressed by applicative means-for example through the use of cookies/post data. The first difficulty with this approach is that HTTP is a stateless protocol. This means that each HTTP request is not related to any other request. Web servers and browsers communicate via HyperText Transfer Protocol (HTTP) messages, so Finesse and other web applications wrap XMPP messages inside of HTTP messages. Browsers don’t support XMPP over Transmission Control Protocol (TCP) natively, so all XMPP traffic must be handled by a program which runs inside the browser. If a web application needs to work with XMPP, multiple issues arise. Unique identifier used to link a request with a response for stanzasĭefines the default language for any human readable XML in the stanza There are three core stanzas in XMPP:Īll stanzas have to and from addresses and most stanzas also have type, id, and xml:langattributes.

A server would typically just be defined by the domain, a conference room defined by and a client by messages are called stanzas. Note: All three JID components are not used in all cases. Identifier of the user's specific entity/endpoint (e.g., laptop, smartphone, etc), a session identifier, or pubsub node name XMPP server fully qualified domain name (FQDN) XMPP/Jabber is extensively used in instant messaging (IM) and presence applications.Īll XMPP entities are identified by their Jabber ID (JID).Ĭlient username on the XMPP server or name of the conference room XMPP allows for fast delivery of small pieces of structured eXtensible Markup Language (XML) data from one entity to another. Understanding Finesse BOSH Implementation Understanding XMPPĮxtensible Messaging and Presence Protocol (XMPP) (also known as Jabber) is a stateful protocol in a client-server model. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration.
