If HTTP had that requirement and all servers followed it, then the risk of DNS rebinding attacks would be eliminated. Servers don't always know what domains they're expected to serve -- if I sudo apt-get install lighttpd and already have a domain name pointing to the server, I expect that domain name to work with no additional configuration. And this is how all the web servers I've used actually work. So, I imagine this requirement is infeasible.Received on Tuesday, 9 February 2010 19:47:25 UTC
