Enabling HTTP Strict Transport Security on debian servers - I just enabled HTTP Strict Transport Security (HSTS) markers on a bunch of web servers that offer HTTPS. It's an easy step to take, and it means that users of HSTS-compliant browsers (such as Chromium and the upcoming Firefox 4) or browsers with HSTS-compliant extensions (like Firefox's NoScript or HTTPS-Everywhere) will no longer be vulnerable to attacks like sslstrip once they have made one successful connection to the HSTS-enabled HTTPS web site.
multiple ssl auf einer ip ist ja nix neues, hier aber sorgt gnutls dafür, dass man auch verschiedene certs nehmen kann
