Ah, where the web is going. 8e6 Technologies sells a hardware box that it claims does signature analysis to detect HTTP proxies and blocks them. It can also block HTTPS proxies "that do not have a valid certificate" (whatever that means), as well as do such things as block IM, force Google and Yahoo searches to be done in Safe mode, and so on. They're marketing this to the education community (with the typical horror stories of the problems your school district can run into if students use proxies to get around your rules). What I find most interesting, though, is that the company, based in California, has an overseas presence in exactly two other countries: Taiwan and China. One doesn't need much imagination to see what market they are going after there.... -- Jerry --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majordomo@metzdowd.com ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE
