The IESG has approved the following document: - 'HTTP Random Access and Live Content' (draft-ietf-httpbis-rand-access-live-04.txt) as Experimental RFC This document is the product of the Hypertext Transfer Protocol Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Barry Leiba. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-httpbis-rand-access-live/ Technical Summary Traditional HTTP range semantics allow the request of ranges with fixed starting points but undefined ending points. However, responses must not be open ended in this way - they can indicate that the full representation is open ended but the range response itself must be finitely defined. The draft discusses this in section 2.2 This document defines a backwards compatible mechanism for streaming open ended response ranges (i.e. ranges that start at a fixed point but are appended to and transferred after the response headers have been generated). It is applicable to all versions of HTTP. Working Group Summary There was consistent, but low level, interest from the working group in this document. It was discussed in several dozen email messages and at least 3 times in face to face sessions with concrete discussion each time. The initial mechanism was agreed to quickly and much of the discussion focused around use cases, examples, and whether or not Experimental is the right status for the document. There is no controversy around this document within the working group. Document Quality Participation in the document's review and development was acceptable: involving about 10 individuals representing browsers, servers, and intermediaries. The Working Group Last Call reassured the chairs that there was sufficient broad based interest to move the document forward. There is at least one implementation of this on a large content provider currently deployed. Personnel Patrick McManus is the document shepherd; Alexey Melnikov is the responsible Area Director.
