How can Drupal automatically authorize a user on the site if he has a cookie from another resource?

Question

PHP

Good afternoon,
Does anyone know how to organize automatic user authorization on the site if he has a cookie from another resource.
Something simple in the form: if there is a cookie, we browse the site as an authorized user, if not, then as a guest.
Thank you.

Answer 1

Yeah, of course...
Is this a big joke, or do you really not understand?

Answer 2

Before asking a question, you must first try to "register a domain", and see what happens.
After that, google about cross-site authorization.
In short - without the participation of that site, nothing will work. You can, for example, show a picture from it, with a unique parameter. So the browser will send its cookie requesting this picture.
Next, that site should make a request to this one, passing authorization information for the owner of the cookie.
Read this manual only if you have a clear understanding of the difference between a browser and a server.

Answer 3

Will a cookie be created on the "other" resource with the registered domain of the site on which it will be used? Or I really just don't get it...

Answer 4

no way

Answer 5

Thanks for the advice.
But what if we assume that both the drupal site and the site that creates the cookie are on the same domain. Are there ready-made solutions for drupal?

Answer 6

if on the same domain, then you can try to do .... Drupal has a jquery.cookie out of the box, to which you can set properties relative to the domain.
