Is it possible to create a cookie yourself?

Question

JavaScript

There is only one question, but it applies to both js and nodejs. Is it possible to manually create a cookie so that the server recognizes it as native? That is, it is possible to pass "something" in the parameters from the browser, which will be perceived as a cookie? And the same goes for the node, is it possible to pass "something" in the parameter without setHeader so that another server sees the cookie in this?
And most importantly, how?

Answer 1

Of course you can, this is usually done with automatic authorization somewhere
