Localization plugin issue?

Hello, there:
  I am using "Localization plugin" to help my app support both English
and Chinese.

  However, I dont find the way to switch the language version without
interfering other users from client side.
  My way is adding a button, which links to an action, to change the
variable "Localization.lang" 's value, but if one user switches from
English to Chinese , it does affect all the other current users, their
browsers also switches to Chinese!
  Any good idea?

Thanks a lot!

hi, i use this plugin too and don't have your problem. you should keep
language in a session or cookie variable.

  Yap, I thought of using session or cookie, but I dont know how to do
that, I will try google it :). Thanks a lot!
