How would you feel, if you issued :
import urllib urlopen("""https://server.domain.com""").read() and the command got you data from some other URL without telling you! You use firefox, and the site is different than the data you got! Same with chrome. Safari. Even IE ! Cheated? (Well I was mad -- after IE worked). [...] None of them worked! Wow. Then you wonder, whats going on. You poke one of the server administrator, and he sends you the logs, and you see the problem. The keyword being "SNI".
I believe there is a bug in the HTTP server; it doesn't conform to the HTTP/1.1 protocol. Even without the client using SNI, you should still get the right page, since the HTTP Host: header indicates the host you are trying to contact at this point, not SNI. The SNI is only relevant for the certificate that the server presents.
