Request Headers – what client sends to server

ver HTTP 2 — serves in bits and pieces

Status Codes

cookies — pieces of data for (eg: for authentification) that is stored in the user’s computer
authentification token can be stored, and has a ‘time to live’ (like your ic that the govt ids you by)
(called session on the server)

https everwhere: chrome extension to use https if available

private ip address 10…. (companies usually) 172…., 192….
public (router) 128….

‘permanent’ (public static ip address) can be bought for your server

sessionless authentification – id and data stored as encrypted token
doesn’t need a lookup on a session table
jwt – json web token
