What I'm not seeing is how the directories are structured. I get the
feeling from your examples that each circuit is totally independent of
the others. So to make that work each directory would have to contain
all the code for registering/logging in.
Do me a favor. Give me a simple example of your directory structure for
some of the circuits in roomstogo. This is what I'm envisioning your
directories to look like:
/products
/products/users
/customerservice
/customerservice/users
/users
I'm picturing that "/users" directory is under each circuit that needs
it and each one contains the same code for registering and logging in
etc. Is that how you're doing it?
