Most of us would use url.id, url.isbn and url.volume. You could also
use url['id'], url['isbn'] and url['volume'] if you like on any version
of ColdFusion released this century.

<cfdump var="#url#"> may also be informative.

I.E. you are working to hard if you are trying to parse
cgi.http_REFERER. ColdFusion has already done this and dumped
everything into the URL structure. Of course, if I was going to use a
CGI variable, I would use cgi.query_string and parse as nested lists.

But is 'test.cgi' a ColdFusion template?

Use list functions. The url is a nested list. The outer list has an ampersand delimiter and the inner lists have an equal sign delimiter.
