they have to.
My browser has a setting that tells it how often it should check to
see if a site has been updated. For example, I set it for 12 hours.
If I go to the site 6 hours after the last visit, it simply pulls the
page from the cache. If the site was updated in that 6 hours, I miss
the update unless I manually refresh the page.
I would suspect most people don't know such a setting exists. They
may unknowingly have it set for something like a week. In which case
their browser wouldn’t go looking for an update until after you’ve
updated the site seven times.
There must be a way to override this setting and make the browser
look for a new page each request. News sites and weather report
sites must use something so the visitor gets a new page each time,
but I don’t know what it is.
