This is the wiki home of the IETF HTTPbis Working Group. We're chartered to:

  • Revise and clarify RFC2616 -- the HTTP 1.1 specification -- to improve interoperability and security, and
  • Develop the next version of HTTP -- HTTP/2.
Looking for HTTP/2?
See the HTTP/2 Home Page.

Other HTTP-Related Work

We track other items for potential work (as allowed by our our charter) as PotentialWork.


As with all IETF Working Groups, almost all discussion and decisions are made on our mailing list. Joining this list is "joining" the Working Group, and is the best way to participate.

We meet at least twice a year at IETF meetings; see also materials from past meetings.

During our official meetings, we use an XMPP (Jabber) channel at xmpp://httpbis@jabber.ietf.org?join (archives) provided by the IETF.

ALL contributors and participants in the Working Group (i.e., on the mailing list and in physical meetings) MUST read and understand the NOTE WELL statement.
