Just wondering...instead of a blanket redirect and then location that 
try to overide it, would it be better to have a rewrite that says "if 
not subdir1|subdir2|myfacebookapp rewrite to http". Then locations for 
those subdirs if they require passwords, etc.

How would I do the if not subdir1|subdir2|myfacebookapp rewrite to http 
check?
