UPDATE: I've added a META Expire tag to the page headers. We already had a META no-cache tag in place, though, so we'll see.</font>
I've done some more investigation on this. While the httpd-equiv tags may work for some proxy caches, it won't work for others. The only standard way to specify no-cache is
in the HTTP headers. A proxy is not required by any standard to search the text of a document to see if any httpd-equiv tags have been inserted in it. It's expensive on resources, so ISP proxies (such as mine) don't do it.
If Flyertalk's web server issued the no-cache directive in the HTTP headers, everything should be fine. Inserting the httpd-equiv tags in the documents is a hit and miss solution. (... so to speak.)
