Hopefully I can explain this correctly:
So when a user logs in, there is an area of html markup that display their account information. Otherwise it shows login buttons. I'm noticing that this area is cached, so if someone logs in and it refreshes the page, the login and register button are still show - it should be showing account information. The system knows I'm logged in (if I visit a page I haven't before, then the correct markup shows). Is there any way I can prevent this area from being cached or having the cache clear when a user logs in?
