Learn how the If-Modified-Since and Etag: headers work. And of course the Cache-Control... I think the only case where you really need page that is not cached is where you put the current timestamp into the (x)html instead of using e.g. javascript. -- Matus UHLAR - fantomas, uhlar@xxxxxxxxxxx ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
