## Author Notes:
## 	Tested on 1.4.12
##
##  This file is intended to be a guide to redirecting users to a subdomain
##  when they log in into an integretad system with phpbb
##
##  This come from my use of coppermine and phpbb
##  as a bridge to authenticate coppermine users. Everything was fine until a
##  change my configuration to use subdomain instead of one like usual.
