I've found out that our XF board does not handle the www and non-www logging-in properly. Let's say a user enters: domain.com and logs in; and then clicks a URL that begins with www.domain.com/threads/.... , then the new page that opens has already logged out the user. I know that technically, www and non www domains are technically two different addresses. But is there a way this can be fixed? Say, even if the user enters domain.com, he/she should be directed to the www version? I'd like to enforce www in my domain addresses.
