actually!)
Thanks!

I've done it before but showing the place in a hierarchy - you can do
this with the ancestor:: axis in XSLT.
As to your requirement, how about a little flowscript and JXTemplate:
function yourpage() {
var yourURL = cocoon.parameters["URL"];
var breadcrumbs = session.getAttribute("breadcrumbs");
if (breadcrumbs == null) {
breadcrumbs = new java.util.ArrayList();
session.setAttribute("breadcrumbs", breadcrumbs);
}
breadcrumbs.add(yourURL);
cocoon.sendPage("yourURL", {"breadcrumbs" : breadcrumbs});
}
Something like that. Not sure about the exact syntax, but it is more or
less there I guess. All you're doing is storing an ArrayList in your
session, and each time a page is viewed, add the URL to your array
list.
Then this array list is passed into the JXTemplate, where it can be
iterated over with <jx:for-each>.
Make sense?
