Every time one runs update.php, there is a side effect of causing the
Last-Modified: Thu, 03 Feb 2011 00:20:37 GMT
HTTP header of Special:RecentChanges to get reset, and probably also
that of RSS feeds.
Understand that many programs e.g., WWWOFFLE, monitoring this date will
thus cause a false notification to their user, who then looks to find
nothing changed in RecentChanges.
Also notice that on high use wikis like Wikipedia, one wouldn't be aware
of the problem, but on low use wikis, one certainly will.
Don't just assume that Last-Modified should be updated without a valid reason.
I won't even get into the waste that is caused by resetting the
Last-Modified header on a RSS feed.
