Is it possible to go to the VK page of a user who has visited my site?

Question

In contact with

When a user enters my site, I need to get the data of the VK page (at least the id) with which he is logged in at the moment.
Maybe there are some ways if the tab with VK is not even open? Or maybe this is possible if my site was visited by a link that was opened from VK?
I thought I could somehow look through the http headers, but there is nothing like that.

You can try using pixel retargeting .
