I'm developing an android chat client, I decided to use XMPP and I started studying from the official XMPP RFC. The 7th chapter is about Resource Binding.
Now, for me it's clear the way that Resource Binding is technically realized but I really can't understand for what it could be useful.
To be more clear and straightforward:
- what usefulness can it have on the chat client?
- why should a chat client use this feature?
- what usefulness can it have on the chat server?
- why should a chat server use this feature?
I read the guidelines of stackoverflow. I'm not asking for an opinion. I would like to have an explanation of how and why this feature could/should be implemented in an application.
