Does anyone know of a relative simple mechanism

page1 > page2 > page3
Any hints or pointers also welcome!
 

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?
