Hello. We place ads on the forums. Links pass through our tracker. So it turns out that I see the cookies of this forum. Session minimum. From their banner there is a redirect to them (apparently also track), and then to us. It is worth noting that this happens when for some reason we have HTTP 1.0 set to $ _SERVER [SERVER_PROTOCOL]. The forum works for them on https. How is this possible? Maybe in http 1.0 cookies are not bound to domains. Does not depend on the browser (user agents are different) I tried to reproduce the bug, but it did not work out. At least push where to dig.
UPDATE. An example of such a user.
Always have such a bug [SERVER_PROTOCOL] => HTTP / 1.0.
Another strange thing is that Referer is equal to the link to which it came.
Maybe some proxy curves yuzayut.
