Can you explain what is meant by the structure of requests in client or server applications?

The structure of requests in client or server applications is the organization and format of data sent and received between the client and the server.

It includes:

• Request method: for example, GET, POST, PUT, DELETE in HTTP.
• Headers: request metadata such as content type, authorization, cookies.
• Request body: data transmitted, such as JSON, XML, or form-data.
• URL parameters: additional data passed in the query string.

Example of an HTTP request:

POST /api/users HTTP/1.1
Host: example.com
Content-Type: application/json
Authorization: Bearer token

{
  "name": "Ivan",
  "email": "ivan@example.com"
}

A correct request structure ensures proper interaction between the client and the server, facilitates data processing, and enhances security.
