CSS History Stealing Acts As Cookie

CSS history stealing repurposed as a persistent cookie substitute. The site forces a visit to a per-user unique URL, then on return iterates candidate URLs to recognise the visitor. Matan Gillon's refinement uses a ten-deep tree of virtual folders to hold 10^10 identities in 100 probes, defeating cookie deletion and shared-proxy IP collapse.
