Dunno if this is a FAQ, but at least I know the answer…
User came to me today with two questions about RT and Opera. Firstly,
he found that clicking “Home” would seemingly log him out; second, he
found that clicking “Show brief headers” after "Show full headers"
would bring back a very different view of the ticket history.
Both of these were traced to problems with Opera’s caching: for
the first problem, a refresh would take him from the login screen
to the proper home screen.
Maybe we need no-cache headers on some of the pages, or maybe Opera’s
just trying to be too clever for its own good. One to be aware of,
anyway.

a no-cache directive got added in 2.0.8. (or was it 2.0.7?) That
should take care of that.

Opera is being too clever. It blatently ignores any no-cache or
expires headers in HTTP responses. I consider it a bug, and it makes
for using dynamic data services (such as RT) difficult.

Huh, that’s odd. I’ve used Opera as my only browser for some time now,
and I have no problems. Perhaps you haven’t allowed cookies from the site?
That was a problem a lot of my peers had…

No; Opera definitely ignores no-cache and expires header times. I
have an application that clearly demonstrates it, since I know these
headers are being sent on certain pages. Heck, even Netscape 4.7x
gets this right!
With RT, it just means I have to hit reload quite often to get the
refreshed dynamic pages, especially when I hit the “Home” button.

Oh, right. My preferences are set such that I just never cache anything.
It never seems worth it, I always seem to want to reload things. That’s
what you get when you work for a university with gigabit ethernet, I
guess.
What about using opera’s automagic refresh to combat that issue?
