Welcome to the HTTP Basics section of the Tutorial Web App. Here, we'll cover the fundamental concepts of HTTP, which is the protocol used for web communication.
What is HTTP?
HTTP stands for Hypertext Transfer Protocol. It's the foundation of data communication on the web. When you type a URL in your browser, your computer sends an HTTP request to the server, and the server responds with an HTTP response.
HTTP Request
An HTTP request is sent from a client (like a web browser) to a server. It includes information about the client, the requested resource, and other metadata.
- Methods: The HTTP method indicates the action to be performed on the resource. Common methods include GET (to retrieve data), POST (to submit data), PUT (to update data), DELETE (to delete data), etc.
- Headers: These provide additional information about the request, such as the content type, language, and caching preferences.
- Body: The body contains the actual data being sent, such as form data or JSON payload.
HTTP Response
An HTTP response is sent from the server back to the client. It includes the status of the request and the requested data.
- Status Code: This indicates whether the request was successful or not. For example, 200 OK means the request was successful, while 404 Not Found means the requested resource was not found.
- Headers: These provide additional information about the response, such as the content type, content length, and caching directives.
- Body: The body contains the requested data, such as HTML, JSON, or XML.
