I’m sorry if I don’t find similar threads in the forum.

How to avoid multiple connections to a site, from the same IP?
I mean, I just want one connection per device.

thank you

You could catch the IP address in Session.open and drop the connection

But many offices, schools and even apartment complexes will use the same IP address and NAT. So unless you have a very unique use case you might be creating a new problem.

Would a cookie work?
