You can access it by suffix = slingRequest.getRequestPathInfo().getSuffix();
Suffix output will be = adobe/day/cq
Appreciate it, you got me 90% there. When I ran you're test it didin't work, the suffix was null.
However when I ran it with geo/en/home.html/adobe/day/cq which is what sling describes as a suffix it returned "/adobe/day/cq" as described.
Bailey, I apologize for misleading. There is no # in between. You are using the right way.
