HTTP & Sessions One of the main protocols (rules that govern how computers communicate) on the web is called HTTP. HTTP is what is known as a stateless protocol. This means that it doesn't 'remember' things. It's a bit like having a conversation with a goldfish. You can ask a question and get a reply, but when you ask a follow up question, the original has already been forgotten, as has who you are and what you were talking about. So if HTTP is stateless, how come my news site remembers to give me the weather for my home town, my preferred South American river based online store tells me when it's time to order more multivitamins, and I'm justifiably proud of my #100days success streak? The answer is......... Sessions Sessions are a way of storing files on your computer that allows a website to keep a record of previous 'conversations' and 'questions' you've asked. By using sessions, we can store this info about the user to access later....
