I have two domains, namely hk-forum.net and foyer.biz.
I have rented a hosting place, which offers me one domain name only.
foyer.biz is the main domain name.
As I am so poor that I have no money to rent one more hosting place (actually I need to rent a dedicated server for the forum...), I decided to share the hosting place with the two domains.
I use "URL Frame" (or Mask URL) in NameCheap.com to redirect hk-forum.net to www.foyer.biz/hk-forum.net/
However, the cookie set by the scripts of hk-forum.net doesn't work.
What domain name should I set in cookie in order to make the cookie works?
