Many links go to a specific HTML page, and unless some scripting such as a JavaScript on the page modifies the result of clicking, say to serve a page suited for full-screen PCs to desktop users and a different page optimized for hand-held devices to certain detected conditions, the link will always deliver the same results till the actual HTML page it leads to is modified.
But the link you quoted is not to a fixed object. It instead links to a CGI script that searches for results matching a specific criteria. The results it serves are dynamically generated from a search of a database, and every time the data in that database changes, what that link yields will change accordingly. The clue to this is the question mark in the HREF (Hypertext Reference) of the link. Everything after the question mark is part of something called a query string. That query string tells the CGI script what to do. In this case, since it is a search, the CGI runs a search for a variable named “g” and passes the value “jim+corce” to that variable.
CGI or Common Gateway Interface scripts can be used for all sorts of server-side processing such as accepting, checking and emailing or storing form input; adding form input to a database, searching a database and much, much more.
