Looking at alternative hostnames on SSL certificates

It's possible for a single SSL certificate to support multiple domains (not just wildcard domains like *.google.com). If you're interested in examining the other hostnames affiliated with a certificate, you can use the normal Windows certificate properties window.

In Chrome, you can get to that window by clicking the padlock or page icon next in the address bar, switching to the Connection tab, and clicking Certificate information. In the resulting window, switch to the Details tab, and selecting the Subject Alternative Name item.

It appears that Blogger at one point was accessible at blogblog.com, but going there now produces a Google-themed error page.
