Answer from AI
Main features of the HTTP/1.1 protocol:
-
Persistent Connections: by default, the connection between the client and server is kept open for multiple requests/responses, reducing the overhead of establishing connections.
-
Pipelining support: the client can send multiple requests in a row without waiting for responses, although support is limited and not always used.
-
Caching: HTTP/1.1 enhances caching capabilities with headers like Cache-Control, ETag, and others.
-
Range Requests: allows requesting parts of a resource, useful for resuming downloads.
-
Additional methods: besides GET and POST, methods like PUT, DELETE, OPTIONS, HEAD, etc., are supported.
-
Enhanced headers: new headers introduced for managing connections, content, and authentication.
-
Status codes: an extended set of HTTP status codes for more precise information about the request result.
HTTP/1.1 is an evolution of HTTP/1.0 with improved performance and functionality, but it does not support multiplexing, which was introduced in HTTP/2.
