[http:// | [http://xmpp.org/extensions/xep-0124.html BOSH] (or HTTP binding) is a technique designed for asynchronous XMPP communication between client and server using HTTP. Unlike Jabber HTTP Polling ([http://xmpp.org/extensions/xep-0025.html XEP-0025]), it uses multiple request/response pairs to improve responsiveness and avoid unnecessary polling. Besides client and server, there is a Connection Manager entity in BOSH architecture, that serves as a mediator handling HTTP requests from clients and communicating with server. Client communicates with CM via HTTP-POST requests/HTTP responses defined in mentioned XEP and CM communicates with XMPP server either acting as ordinary XMPP client or using [http://xmpp.org/extensions/xep-0114.html component] protocol. For sake of server-initiated XMPP messages there should be always a HTTP request pending in client-CM connection. In practice, CM can be standalone HTTP server or extension of XMPP server ([http://xmpp.org/extensions/xep-0124.html#technique more on the technique]) | ||
