Maybe this isn't the
best place for this question/discussion but I use CodeIgniter for all my projects and I've been a fairly active forum user over the years so I thought I'd give it a try...
I know that browser caching is really important for speeding up page loads, reducing the amount of requests to the server, reducing bandwidth etc. BUT ... it's really annoying too! The fact that visitors have to refresh the page to see new content means that often they won't be seeing the latest version of a page.
Is this just the way of the world and that's all there is to it? Is there no way to intelligently have the browser check whether the cached version of the page is now out of date? Is that what the Last-Modified header is for?
I've been playing around with different headers but I haven't found an authorative article on the subject so I would really welcome some input from you guys!!!!
