I go to about a dozen comics to start my morning. At home I always get the new day’s comic. Here at work I will often get a comic several days old and will have to hit refresh to get today’s. What must I do to prevent that?

That didn’t seem to do the trick. Or, yesterday it seemed to have worked, but today I had the same old problem.

The problem is probably your work proxy server - if things are slow it may return a cached page while the proxy cache updates - then you get the new page.

Makes sense. I sometimes see pages several days old.

If it’s Firefox, hitting Shift-Reload should force it to get a fresh copy of the page. If a proxy server is doing it, you’ll have to talk to the network guys.
