The method which is used by wikipedia is cache all dynamic pages as
long as possible, but when user update, purge from it.

Example HTTP response:

Status=OK - 200
Date=Sun, 29 Jun 2008 13:59:17 GMT
Server=Apache
X-Powered-By=PHP/5.2.1
Cache-Control=private, s-maxage=0, max-age=0, must-revalidate
Content-Language=en
Vary=Accept-Encoding,Cookie
X-Vary-Options=Accept-Encoding;list-contains=gzip,Cookie;string-contains=enwikiToken;string-contains=enwikiLoggedOut;string-contains=enwiki_session;string-contains=centralauth_Token;string-contains=centralauth_Session;string-contains=centralauth_LoggedOut
Last-Modified=Sun, 29 Jun 2008 13:58:08 GMT
Content-Encoding=gzip
Content-Length=15289
Content-Type=text/html; charset=utf-8
Age=45672
X-Cache=HIT from sq27.wikimedia.org, MISS from sq23.wikimedia.org
X-Cache-Lookup=HIT from sq27.wikimedia.org:3128, MISS from sq23.wikimedia.org:80
Via=1.0 sq27.wikimedia.org:3128 (squid/2.6.STABLE18), 1.0
sq23.wikimedia.org:80 (squid/2.6.STABLE18)
Connection=keep-alive

Their usage is simpler as they only need to purge per page, but most
common apps would need to purge per channel as Mark (Yahoo!) pointed
out.

Thanks.
