Haha, yeah, I don't know what happened, but the web host has apparently gotten it into its head starting about a month ago that it can cache the last version of the front page it served. It was REALLY bad for a couple days, and now just seems to happen occasionally. I have no idea why it thinks that. Goodness knows we are
hardly the only web site in the world that has user logins. I don't know if there's some magical incantation I can put in a meta tag somewhere or something that will make it not do that. I will admit my web fu isn't strong.
It seems pretty harmless, but if that turns out not to be the case and you actually use it to break something, I will be annoyed.
