Hello, for those of you who are interested in doing weird things in Apache, I would like to advertise NetAirt -- a brand new redirection system inside an Apache module. It supports both DNS- and HTTP-based redirection, and can be used to implement Akamai-like 2-level redirection system. And yes, it implements a UDP server inside an Apache module (although with a few-lines patch).
As for replica selection, NetAirt can select topologically-proximal replica servers based to network distance (AS-hops); classical stuff, such as normal DNS operation (name-to-IP), and round-robin address selection is also supported. Available at: http://www.globule.org/netairt/ (src, docs, relevant papers) Live demo: http://lotus.cs.vu.nl/ Comments welcome :-) Enjoy, M. -- Michal Szymaniak | mailto:[EMAIL PROTECTED] | http://www.cs.vu.nl/~mszyman
