I've done Breadcrumbs (sorry, the website is not public yet).
I used the Fusebox method of organizing the CFAS templates. www.fusebox.org
I put each Fuseaction in its own folder.
So, for example, /index.cfm is the Home Page
/HL/index.cfm lists Yellow Page headings (HL = List Headings), for example,
all those that start with "B", and passes to /HL/LL/index.cfm that fact
that the page request came from headings that start with B.
/HL/LL/index.cfm displays the name of all the "Beauty Shops", for example
(LL = List Listings), and passes to /HL/LL/LO/index.cfm the fact that the
page request came from headings that start with "B" AND a heading titled
"Beauty Shops"
/HL/LL/LO/index.cfm displays the name, address, and telephone number of the
beauty shop named "Hair for You", for example (LO = List Organization).
Each of the above 3 levels has enough information to create a Bread Crumb
trail, with active links to any preceding level/page/fuse
This is the brute force way of doing it. There must be a clever way. I
wondered how I might abstract the above and eliminate the need for multiple
directories. But I'm an engineer by training and experience, and we
engineers are usually happy if we can find one way that works well. We're
even happier if we achieve transparency - even if it's tedious to create ;-)
I assume it's obvious that the exact same templates work whether the user
starts with "A" then "Automobiles - New", etc, since all specifics are
pulled out of a SQL7 database. The Breadcrumb Trail displayed then changes
with each different page request.

PS> Fuseboxers will note the directory structure at once does two things:
(1) It implicitly defines the Fuseaction, and (2) It implicitly does the
work of CFSWITCH.
