Yes, the normal action.

The normal action (but modified by some of the options).
pragma-no-cache - To make an unconditional fetch for the page if the
browser forces it.
cache-control-no-cache - Similar to above, but a different method of
forcing.
request-changed - The time since the server was last checked for a
newer version before trying again.
request-changed-once - An option to force the previous option to be
ignored and a once per online session rule used.
request-expired - To make an unconditional request for a page if the
cached one has expired.
request-no-cache - To make an unconditional request for a page if the
cached one asks not to be cached.
request-redirection - To make an unconditional request for a page if
the cached one is a re-direction page rather
than just content.
request-conditional - The option that you need to enable checking for
newer pages on the server without always
downloading the whole thing.
validate-with-etag - The option to use the HTTP/1.1 cache validation
method or not (it doesn't work with many servers).

If you set request-changed-once=yes then WWWOFFLE will only try that
page once while online to see for changes. If you request it again in
the same online session it won't even try looking for changes.
By default WWWOFFLE will make a conditional request for a page so that
it asks the server if a newer version exists without getting the whole
thing. Your statement above will check the server more than once per
online session since it includes an "unchanged since fetched" clause.
The only way to know this is to ask the server. So you need to have
request-changed-once=no.

Yes.

Yes, also pragma-no-cache=yes for older browsers.

Normal behaviour, some servers are broken and require the
try-without-password option.

WWWOFFLE doesn't support digest authentication.
