Pros
-
Informative : Includes status codes and headers for detailed feedback.
-
Flexible : Delivers content in various formats.
Cons

Miscommunication risk : Improperly formatted responses can cause client errors.
Example
HTTP/1.1 200 OK
Content-Type: text/html
Content-Length: 125
<html>
<head><title>Welcome</title></head>
<body><h1>Welcome to our website!</h1></body>
</html>
This HTTP response indicates a successful request with the status code 200 OK. The headers specify the content type (text/html) and content length. The body contains the HTML content that will be displayed to the client, such as a welcome page.
