When the handshake is done, the many conversation between the consumer and server is secured by symmetric encryption utilizing the session key, as well as the browser can make the 1st HTTP GET ask for for the location.

This process follows a 4-layer design, where facts travels in a single course and then from the reverse path when it reaches the destination:

Headers: A set of key-value pairs that will both be standard headers, making use of to The full message; reaction headers, giving added information with regard to the server position; or representation headers, describing the format and encoding for that concept details if current.
