I have a main domain a.com and also added an addon domain b.com
Now I have
b.a.com = a.com/b.com
What I want is not to connect b.com to a.com, I want that b.com to be standalone.
So I have done 2 redirects:
b.a.com -> a.com/404.shtml
a.com/b.com -> a.com.404.shtml
First redirects works, while the 2nd is not working at all. How can I fix that ?
