(June 2008) Interaction Help Bosh is not BOSH Bidirectional-streams Over Synchronous HTTP ( BOSH ) is a transport protocol that emulates a bidirectional stream between Bosh is not BOSH About Wikipedia two entities (such as a client and a server) by using multiple synchronous HTTP request/response pairs without requiring the Community portal use of polling or asynchronous chunking. Recent changes Contact page For applications that require both "push" and "pull" communications, BOSH is significantly more bandwidth-efficient and responsive than most other bidirectional HTTP-based transport protocols and AJAX. BOSH achieves this by avoiding HTTP Tools polling, yet it does so without resorting to chunked HTTP responses as is done in the technique known as Comet. To date, What links here Related changes BOSH has been used mainly as a transport for traffic exchanged between Jabber/XMPP clients and servers (e.g., to facilitate Upload file connections from web clients and from mobile clients on intermittent networks). Special pages For "push", a BOSH client starts an HTTP request, but the server postpones sending a reply until it has data to send. [1] After Permanent link receiving a reply, the client immediately makes another request on the same HTTP connection, so the server can always send Page information Wikidata item data to the client without waiting for the client to poll. If, while waiting for a reply, the client needs to send data to the server, Cite this page it opens a second HTTP connection. There are at most two HTTP connections open at a time, one on which the server can send data as a reply and one on which the client can send data as a POST. Print/export Create a book "Bidirectional-streams Over Synchronous HTTP (BOSH)" and "XMPP over BOSH" are draft standards of the XMPP Standards Download as PDF Foundation. Printable version The second related standard XMPP Over BOSH (XEP-0206) defines how BOSH may be used to transport XMPP stanzas. The Languages result is an HTTP binding for XMPP communications that is intended to be used in situations where a device or client is unable Français Edit links to maintain a long-lived TCP connection to an XMPP server.
