15 Common HTTP response status codes
HTTP stands for Hypertext Transfer Protocol, a standard internet protocol essential to load web pages on hypertext links. In order to successfully load information on the browser transferred from the server, HTTP should be fulfilled.
A typical HTTP request contains; an HTTP version type, a URL, an HTTP method, HTTP request headers, and an optional HTTP body. The HTTP request will be in the form of encoded data that a server can understand and process it. HTTP comes with an extra security layer called HTTPS created by SSL service providers that encrypt the data sent/received through the server. SSL provides complete security for the information transferred and prevents leakage of data to unauthorized users or hackers.
