HTTP Request

An HTTP request is a message sent by a client to a server to request data or perform an action.

Browsers, APIs, mobile apps, and automated tools all use HTTP requests to communicate with web servers.

How Does an HTTP Request Work?

A typical request process looks like this:

1. The client sends a request to a server.
2. The request includes a method, target, and headers.
3. It may also include a request body.
4. The server processes the request.
5. The server returns an HTTP response.

Main Parts of an HTTP Request

An HTTP request usually contains:

• Method: Defines the requested action.
• Path: Identifies the target resource.
• Headers: Provide metadata about the request.
• Query parameters: Add optional request values.
• Body: Sends additional data when needed.

For example:

GET /products/1001 HTTP/1.1
Host: example.com
Accept: application/json

HTTP Request Methods

Common request methods include:

• GET — retrieve data
• POST — send or create data
• PUT — replace a resource
• PATCH — update part of a resource
• DELETE — remove a resource

The method tells the server what the client wants to do.
