[ic] Two different domains, one for front door, other for checkout.

[Rick Bragg]

I want to run the same catalog under 2 domains, one for regular traffic, 
and the other for secure checkout.

say:
catalog at: http://www.xyz.com
checkout at: https://www.abc.com/xyz.com
(fictitious names)

The above is already set up and points to the same site using Apache aliases

However:

http://www.xyz.com/cgi-bin/catalog
(works fine)

https://www.abc.com/xyz.com/cgi-bin/catalog
(error)
"Undefined catalog: /xyz.com/cgi-bin/catalog"


Again, I already have apache set up with aliases and apache is not the 
problem.

My interchange.cfg looks like this:

Catalog catalog /usr/lib/interch/catalogs/catalog \
/cgi-bin/catalog \
/xyz.com/cgi-bin/catalog \
/catalog

Any help would be appreciated!
Sorry about the second posting, this is just to clarify. the last was a 
bit confusing.

Thanks
Rick
