http://trac.tools.ietf.org/wg/httpbis/trac/report/9

Current Work (not in -09) (1/2)

• Age Calculation: made the age calculation algorithm a bit less conservative; this needs more eyes (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/29)
• Fragment combination during redirects: ongoing discussion whether this is up to HTTP to specify, or whether it depends on the media type (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/43)
• Status codes and caching: clarify heuristic caching of responses (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/110)

Current Work (not in -09) (2/2)

• The return of the Sniffing discussion: TAG asks for Security Considerations of ignoring Content-Type (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/155)
• Case-sensitivity of dates: ABNF makes them case-sensitive, reality is they aren't, and prose asks implementers to do this already (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/165)
• Define the term "effective request URI" and use it throughout (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/196)

Pending Issues (1/3)

• Clarification of "deflate" (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/73)
• Multiple Content-Length headers (security!) (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/95)
• Methods and Caching (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/139)

Pending Issues (2/3)

• Keep-alive and Proxy-Connection Headers (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/158)
• Trailer Requirements (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/193)
• Max-Forwards vs Extension Methods (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/203)

Pending Issues (3/3)

• Controversial: error handling for non-URIs where URIs are expected, such as Location header (http://trac.tools.ietf.org/wg/httpbis/trac/ticket/185)
