Historical reference
HTTP and HTTPS: archived explainer
A historical introduction to browser–server communication and encrypted website connections.
Browser and server communication
The original article introduced HTTP as the protocol through which a browser requests a page and a server responds. It contrasted an unencrypted HTTP connection with an encrypted HTTPS connection.
What the original article explained about HTTPS
The guide described an encrypted connection between browser and website, established through a handshake. Its central educational point was the protection of information while it travels between those endpoints.
Read the original claims in context
The old article also discussed certificates and search visibility. Those comments are not reproduced as a guarantee that a site is trustworthy or that using HTTPS will produce a particular ranking. This archive preserves the protocol comparison; it does not verify the security of a particular website.
