I had a commenter on my site complain that when they posted a comment, and hit "post", they were taken back to the individual entry page, but their comment did not appear until they mannually refreshed the page.
I haven't confirmed this as a problem, but, off the top of your heads, what might be causing this?
Basically, yeah. Its saying that the page 'expired' on dec 2000 and should be reloaded instead of cached. It would be nicer to be able to tell the browser in the request to refresh (in the http header content) but we could only do that if we made the page a cgi script, vs static html.
The other tags tell the browser not to cache the page. Since this problem should only be because of comments/karma, we could probably fine tune which pages it appears on. <META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE"> <META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE"> from page: www.i18nguy.com/markup/metatags.html
But thats doable through the templates. I can see where people might not want the main page updated every time, but even that page has dynamic stuff like how many comments are on a post, etc.
