When a user enters the URL of a web page, the website is loaded. If you wish to know what happens behind the scenes, then here are the steps:
Step-1: User enters URL (Uniform Resource Locator) in a web browser.
Step-2: Web browser creates a HTTP (Hypertext Transfer Protocol) request for the appropriate Web server.
Step-3: Web server maps this request to a particular file.
Step-4: This file is returned as a HTTP response to the web browser. HTTP header in the response shows type of content to be displayed. For this task, MIME (Multipurpose Internet Mail Extensions) is used.
Step-5: User views the webpage.
