Hey there! I just wanted to clarify a common misconception about page refreshes. Contrary to popular belief, hitting "Refresh" does not necessarily reload everything from scratch, even if it's in the cache. It would have been so convenient if that were the case, right? Unfortunately, pressing F5 doesn't always trigger a complete page overhaul.
If you take a look at the network tab in tools like Firebug, you'll notice that after hitting F5 on websites like XKCD, certain resources like images may return a status code of 304, indicating that they are "Not Modified". This tells the browser to simply use the cached version stored locally on the user's device since the server hasn't made any changes. In fact, many types of files such as images, scripts, CSS, and static HTML files are typically cached and won't be re-downloaded with a simple F5 refresh.
So, if you truly want to give your page a thorough "refresh," you'll need to clear your cache using shortcuts like CTRL+SHIFT+DEL or other options available in your specific browser settings.
