hi everyone, I just want to know whehter it is possible to detect
a account has been logined or not before I login it in my program.
My program is based on web, so the user can use different browsers
to connect my server and login the account. But now, I meet some
errors, when I open two different browsers and input the same username
and password. They all can be logined. But when I try to send a message,
none of them work. I know xmpp account can be logined in different place
at the same time only if they have different resource. But in my case, the
two same account have the same resource…I think maybe it is the problem.
Thanks for your help
