Introduction
HTTP (Hypertext Transfer Protocol) is a protocol that allows clients and servers to communicate with each other. It is the foundation of the World Wide Web and is used to transfer data between web browsers and web servers.
HTTP Requests
An HTTP request is a message sent from a client to a server. The request contains information about the resource that the client is requesting, such as the URL of the resource and the HTTP method that the client wants to use.
The most common HTTP methods are:
- GET: This method is used to retrieve a resource.
- POST: This method is used to create or update a resource.
- PUT: This method is used to replace a resource.
- DELETE: This method is used to delete a resource.
HTTP Responses
An HTTP response is a message sent from a server to a client. The response contains information about the request, such as whether the request was successful and the requested resource.
The response also contains header information, which can be used to provide additional information about the resource, such as its content type and length.
HTTP Request-Response Cycle
The HTTP request-response cycle is the process by which a client and server communicate with each other using HTTP. The cycle begins when the client sends a request to the server. The server then processes the request and sends a response back to the client.
The following diagram shows the HTTP request-response cycle:

HTTP Request and Response Examples
Here is an example of an HTTP request:
GET /index.html HTTP/1.1 Host: example.com This request is asking for the HTML file at the root of the example.com website.
Here is an example of an HTTP response:
HTTP/1.1 200 OK Content-Type: text/html <!DOCTYPE html> <html> <head> <title>Example Website</title> </head> <body> This is an example website. </body> </html> This response is successful and contains the HTML file that the client requested.
HTTP Methods
The HTTP method that is used in a request determines the action that the server should take. The most common HTTP methods are:
- GET: This method is used to retrieve a resource.
- POST: This method is used to create or update a resource.
- PUT: This method is used to replace a resource.
- DELETE: This method is used to delete a resource.
Other HTTP methods include:
- HEAD: This method is used to retrieve the header information for a resource without retrieving the resource itself.
- OPTIONS: This method is used to determine the HTTP methods that are supported by a server for a given resource.
- PATCH: This method is used to partially update a resource.
HTTP Status Codes
HTTP status codes are used to indicate the success or failure of an HTTP request. The most common HTTP status codes are:
- 200 OK: The request was successful.
- 400 Bad Request: The request was invalid.
- 404 Not Found: The requested resource could not be found.
- 500 Internal Server Error: An error occurred on the server while processing the request.
Other HTTP status codes include:
- 301 Moved Permanently: The requested resource has been permanently moved to a new location.
- 302 Found: The requested resource has been temporarily moved to a new location.
- 401 Unauthorized: The client is not authorized to access the requested resource.
- 403 Forbidden: The client is forbidden from accessing the requested resource.
- 503 Service Unavailable: The server is currently unavailable.
HTTP Headers
HTTP headers are used to provide additional information about an HTTP request or response. Some common HTTP headers include:
- Content-Type: This header specifies the type of content that is being sent in the request or response.
- Content-Length: This header specifies the length of the content that is being sent in the request or response.
- Location: This header specifies the new location of a resource that has been moved.
- Set-Cookie: This header is used to set a cookie on the client's computer.
Other HTTP headers include:
- Accept: This header specifies the types of content that the client is willing to accept in the response.
- Authorization: This header is used to authenticate the client to the server.
- Cache-Control: This header specifies how the response should be cached by the client.
- Referrer: This header specifies the URL of the

What is HTTP? In short, HTTP stands for HyperText Transfer Protocol — and it's used to structure requests and responses over the internet. Whenever you access a site and load and interact with its content, you're using HTTP.
In this video, we break down HTTP and the different processes that take place to make actions on the internet work smoothly. We also take a look at different types of HTTP requests.

HTTP is a request-response protocol, which means that for every request sent by a client (typically a web browser), the server responds with a corresponding response. The basic flow of an HTTP request-response cycle is as follows: Client sends an HTTP request: The client (usually a web browser) initiates the process by sending an HTTP request , .

HTTP is a client-server protocol: requests are sent by one entity, the user-agent (or a proxy on behalf of it). Most of the time the user-agent is a Web browser, but it can be anything, for example, a robot that crawls the Web to populate and maintain a search engine index. Each individual request is sent to a server, which handles it and , .

Think about an HTTP request as your browser connecting to the server and either asking for a specific resource or sending data to it. There are several types of HTTP request methods, which completely alter the type of response that you get from the server. The most common ones are: GET. This is the most frequently used HTTP request method by far. .
