I have been brought up the issue of the date string used in the If-modified-since header. Current practice is to use the Last-modified header, and given clock skew, it's also the only foolproof way to do IMS requests. Could the wording in the spec be changed to reflect that, and eliminate this source of data incorrectness? Basically, change the semantics of "If-modified-since" be "In-not-equal-last-modified". Netscape servers and proxy were changed to use an equality check, because there were cases, with older software, incorrectly set timezones or machine times and daylight savings times where the dates would be off and stale data would be rendered up-to-date.
