Hi Peter, Apropos File URI scheme, if you are saying about accessing a file with something like file://abcd... in a link, 'over a network', then most of the browsers (perhaps all) do not follow "file:" links on a page that is fetched with "HTTP". The purpose is "security" or to prevent a remote page from executing a program on the visitor's computer. The file: links work on pages that are local files on the user's disk! Though in some browsers these settings can be changed. That is why the Opera exploit through file://abcd.... does not work on network. Hope it answers your query! -- Thanks & Regards, Rishi Narang | Security Researcher Member, Evil Fingers Vulnerability Research Analyst, Third Brigade Labs Blog: www.greyhat.in | Associations: www.evilfingers.com | www.thirdbrigade.com ... eschew obfuscation, espouse elucidation.
