Statelessness in HTTP

The HTTP protocol does not contain a direct way to make the server remember us. This means that when you see a loaded page in your browser, at that moment the server has long since processed our request, immediately forgetting about us.

At the same time, when receiving requests, the server cannot distinguish whether these requests were sent by one client or different ones. That is, moving through the pages of the site, when opening each new page, the server does not know whether we have performed any actions on the site or not yet.

In real life, as you know from personal experience, websites remember us. We can log in to a website, add products to an online store, and so on. This is done using special workarounds that allow the server to distinguish clients. We will study these ways further.
