What methods are used for information exchange in the HTTP protocol?

In the HTTP protocol, information exchange is carried out using methods (HTTP methods), which define the type of operation performed on the resource. Main methods:

• GET — request to retrieve data from the server.
• POST — send data to the server to create a resource or perform an action.
• PUT — update an existing resource.
• DELETE — delete a resource.
• HEAD — get only response headers without body.
• OPTIONS — request supported methods from the server.

Each method is accompanied by an HTTP request and response, where headers and message body are transmitted, ensuring information exchange between client and server.
