Welcome to the HTTP Basics Tutorial! This page provides an introduction to the fundamentals of the Hypertext Transfer Protocol (HTTP), which is the foundation for data communication on the World Wide Web.

What is HTTP?

HTTP is an application protocol that defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to those messages. It's the protocol that powers the web and enables you to access information from all around the globe.

Key Concepts

  • Client-Server Architecture: HTTP operates on a client-server architecture, where clients (like web browsers) send requests to servers, and servers respond with the requested information.
  • HTTP Methods: There are several HTTP methods, including GET (to retrieve data), POST (to submit data), PUT (to update data), DELETE (to remove data), and others.
  • URL: The Uniform Resource Locator (URL) is the address of a resource on the web. It's what you type into a browser's address bar to access a web page.

GET Request

When you navigate to a website, your web browser sends an HTTP GET request to the server. The server then responds with the HTML content of the webpage.

Example GET Request

Here's an example of an HTTP GET request to fetch a webpage:

GET /en/docs/tutorials/http_basics HTTP/1.1
Host: example.com

Response

The server responds with the HTML content of the webpage. For example:

HTTP/1.1 200 OK
Content-Type: text/html

<!DOCTYPE html>
<html>
<head>
    <title>HTTP Basics</title>
</head>
<body>
    <h1>Welcome to the HTTP Basics Tutorial</h1>
    <p>This page provides an introduction to the fundamentals of the Hypertext Transfer Protocol (HTTP).</p>
    <!-- More HTML content here -->
</body>
</html>

HTTP Headers

HTTP headers provide additional information about the request or response. For example, the Content-Type header specifies the format of the content returned by the server.

Example Headers

  • Content-Type: text/html
  • Content-Length: 345
  • Connection: keep-alive
