The only way to be sure what is happening is to get some debugging
output from WWWOFFLE when you are online. This will tell you the
reason that WWWOFFLE decided that it was a good idea to go and get a
new version of the page. The way to get the debugging output is
described in the FAQ.

The options that you have chosen look correct for what you are trying
to do. The age for re-requesting is 500 minutes and you have disabled
re-fetching of pages that are expired or contain headers saying they
are not to be cached. You have even chosen the option to request each
page only once during an online session.
The only option that I can think might be causing the problem is the
pragma-no-cache option (and the unspecified cache-control-no-cache
option that also defaults to 'yes'). These two options will mean that
if the browser asks for a forced refresh of the page then WWWOFFLE
will do it. It is possible that the browser is asking for a forced
refresh. Does it happen with all pages or only certain ones? Is the
problem related to selecting from your bookmarks (some browsers will
do a forced refresh of bookmark pages)?
