overflow community,
I've read several posts trying to solve the problem, but they dont answer my question.
Is there any legal way to find out what events (?) another site sends? I dont ask because of illigal buissness and i am ready to find out more myself as soon as i know what i realy have to look for in terms of topic and methods.
In particular its about advertising and finding out if someone registered on another via a referal link. Like a sign that is sent as soon as the registration (on the other site which is not mine) is completed. I want to find this out during the visit of the client on my site.
I just need to know if such a thing is legally possible and what JS topics i should give a go to find out more.
I hope my post is comprehensible enough. :)
edit: It's not about global variables.
