HTTP: The main IETF standards-track document on the HTTP protocol is RFC2068 on HTTP 1.1. It notes that historically three different date formats have been used, and that one of them uses a two-digit year field. In section 3.3.1 it requires HTTP 1.1 implementations to generate this RFC1123 format: Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123 instead of this RFC850 format: Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036 Unfortunately, many existing servers, serving on the order of one fifth of the current HTTP traffic, send dates in the ambiguous RFC850 format.
Section 19.3 of the RFC2068 says this: o HTTP/1.1 clients and caches should assume that an RFC-850 date which appears to be more than 50 years in the future is in fact in the past (this helps solve the "year 2000" problem). This avoids a "stale cache" problem, which would cause the user to see out-of-date data. But to avoid unnecessary delays and bandwidth indicated in Scenario 2 below, this should be extended to say that a date which appears to be more than 50 years in the past may be assumed to be in the future, if a future date is legal for that field. Scenario 3 indicates that servers may also want to follow these rules. Here is some more background and justification for these arguments. The following headers use full dates: HTTP/1.0: Date: Expires: # can be in the future If-Modified-Since: # required to be in the past Last-Modified: # required to be in the past Retry-After: # can be in the future, also takes # relative time - number of seconds HTTP/1.1: If-Range: If-Unmodified-Since: # required to be in the past Note that clock skew between hosts can lead to confusion here - see the RFC for details. Here are some scenarios of the implications of RFC850 dates, which include stale caches, unnecessary requests for things, which are validly cached, delays for the user, extra bandwidth, and presenting incorrect information to the user. Some cases involve comparisons with the current time, and others may involve comparisons between dates from different sources. The abbreviation "/99" is used to imply an RFC850 date with the value "99" for the year.
RFC850 date from server Scenario 1: If a client gets an Expires /99 date after the year 2000, it should interpret it as 1999, to avoid ending up with a stale cache entry. This is as already specified in RFC2068. Scenario 2: If a client gets an Expires /00 date before the year 2000, and subsequently is faced with a choice to either retrieve the document from its cache or look for an updated copy, it may interpret it as the year 2000, to avoid the unnecessary delay and bandwidth of an extra request. RFC850 date from client Scenario 3: If a server gets an If-Modified-Since /99 date from a client after the year 2000, it should interpret it as 1999 when comparing with the local modification date, in order to possibly avoid sending a full GET response rather than a HEAD response. Note that an If-Modified-Since header must never be in the future.
