Symbolic Links

Hello

I have an alias that symbolically links to my radiant application’s
public
directory. Both are under public_html. I can call the home page by going
to:
http://my.example.com/alias/

But when selecting a child the alias is dropped from the path, like
below:
http://my.example.com/controller/child.

The path should read:
http://my.example.com/alias/controller/child

Any thoughts on how I can make this work? Thanks!!
