HTTP Referer is a part of the Header. When the browser sends a request to the web server, it usually brings the Referer with it to tell the server which page we are linking from, so that the server can obtain some information for processing. For example, if we link to a friend from my homepage, his server can count how many users click the link on my homepage to visit his website every day from the HTTP Referer.

Value: It’s the value what you set.
URL match: It's URL matching when you add a Header,and if the match is successful, the Header setting will be added.Not all URLs are added. For example, if you want to add all websites, use * to indicate all URLs.
