i want to ask about move from head link /lib/jquery/jquery-3.3.1.min.js and change this link to google script src="https://ajax.googleapis.com/ajax/libs/jquery.3.3.1/jquery.min.js.
In this way lot's of people should have it in "cache" and doesn't need to download from our page? What you think? is anybody test this solution? If i good understand this file is "not changed" and should be identical?
