Clicking on a link accesses the associated web page or resource. Method of requesting and transmitting web pages. When a user clicks on a link or enters a url in a browser, a request is sent to the http port (80 or 8080) of the associated web server. The server then responds to clients request. If the request is valid and resource is available -> server transmits resource: otherwise, the server responds with an error message or not at all.
