Is way to know when a webpage is refreshed based on the information in a packet? I ran Wireshark for different websites, and refreshed them when the capturing was in progress. I couldn't find a concrete pattern as to which packet in particular indicates that the page has been refreshed.

There is no guarantee that refreshing a webpage in your browser will actually generate a new request to the server since modern browsers aggressively cache content from servers. Detecting this condition will be dependent upon the specific browser being used and the specific contents of the page being viewed.
If your page is mostly quiet once it is loaded, you can look for another HTTP GET (possibly preceded by a TCP handshake). Most modern browsers allow you to refresh a page without looking at the local cache, so you should make sure you are doing that when attempting this (e.g. in Firefox on Windows, CTRL+F5 is the default shortcut for this).
