I think Henry is right... Please correct me if I'm wrong. - Jim
attached mail follows:
As the title says, this is pretty minor.... The wording for handling the If-Modified-Since header uses a MUST when describing when to send back a 304 response. My understanding of MUST/SHOULD/MAY is that MUST is to be used for requirements neccessary for interoperability or correct functioning of the protocol. Since the sending of a 304 response doesn't impact interoperability or correctness (the protocol is unharmed but less efficient if a server ignores I-M-S and always sends back the data), this should probably be a SHOULD. (And no, IIS doesn't ignore I-M-S. This was brought up to me by a non-Microsoft person writing an ISAPI app). HenryReceived on Thursday, 12 March 1998 04:44:56 UTC
