Sure, but if the page itself is static (as in a conventional mailing
list archive), that won't help. The archive host has to be prepared
to feed *new* pages, not refresh the old one, when accessed.
Might be not that different (although perhaps is an overkill).
There is no much difference in refreshing a page with a click of the user,
and having the browser requesting a refresh with a meta-equiv-refresh if
the underlying page has changed.
I do use the trick with some of my pages, some are CGI scripts which
auto-refresh, but in other cases the page can be modified by a crontab
script (I say overkill because if the meta-equiv-refresh asks for a
refresh every minute, and the crontab updates the page every 15-30 min
most of the refresh will be void)
Consider a standard mailman thread archive like e.g.
https://listmgr.nrao.edu/pipermail/fitsbits/2016-July/thread.html
If somebody will make a new post, and I reload the archive page, I will
see the new message (I use this trick to verify a message was archived
after I sent it).
If one could MODIFY the standard format of the archive page in mailman to
prepend the meta-equiv-refresh (and I do not know how easy is that. I've
never personalised any of the mailman HTML pages although I know for some
is possible, maybe one has to patch code) ... that would do the trick.
