What's the difference between a “GET” request

Question

Is there any difference between doing a "GET" request (type URL and Enter) compared to simply refreshing (CtrlR) the page?

Answer 1

Most browsers ignore the Expires header if we do a "page refresh", yet respect it if we do a "url visit".

However, different browsers have their own way of differentiating "refresh" and "url visit", the only way to be sure is to manually test each one of them.

Answer 2

No, it is not simply a get request, because on a page that you've POSTed to (from a separate form), the browser will confirm with you that you want to refresh the page because it is a POST request.

As for your question, you'll need to provide specifics for debugging purposes.

Answer 3

It is simply telling the browser to repeat the page load, which implies repeating the GET or POST request. Some browsers will inform the server that 304 (not-modified) is an acceptable response, and the server can reply with a 304 HTTP response to inform the browser that it's cached contents are valid
