Ahhhh..... nice waters. Bummer that I had to jump into coming home to snow covered mountain pass closures......

I actually have 5 environments in my big system. I set up vars to choose which subdir I go to, ie:

http://mysite.com/app
http://mysite.com/appTEST
http://mysite.com/appQA

you get the idea.

Once in the env, all links are relative and stay within the env.

If that isnt apparent, point me to examples.
