Well, see my mail. :)
Just add:
Last-modified: <now> Expires: <now>You can add "Cache-control: no-cache" if you're really paranoid. Look at http://www.web-caching.com/mnot_tutorial/ for more info. It's very nice.
Actually, there was a discussion about a year ago. Since then, the swiki sends pages with these three header lines: Expires: 0 Pragma: no-cache Cache-Control: no cache In PWSSwiki this was only done for "edit" requests, because it is fatal if you edit an old version. In ComSwiki, these three lines are always sent. Hopefully, the next ComSwiki version will support a real "Last-modified" header as well as the "HEAD" method.
