ok, so I have a few things going on.
I have maindimain.net as my main domain and the entire site is built on wordpress. I have created weddings.maindomain.net which resolves to maindomain.net/weddings
This works perfectly fine and I am happy with it.
NOW i have another domain called secondarydomain.com which also needs to forward to maindimain.net/weddings
It seems that the problem is that since /weddings isn't a real sub directory and is only a permalink for the maindomain.com/?p_is=123 it is just not working!!
So the question is, how to I make a domain that resolves to a specific page that was built in wordpress???
