Perfect answer for google, but if you are looking to have way more information on webservers, I highly recommend going to www.shodanhq.com, follow the how-to's and you will find incredible information on millions of webservers running ssl and much much more...
Be responsable, have fun.
If you use firefox browser install this addon on firefox https://www.eff.org/files/https-everywhere-latest.xpi this addon will enable https protocol on any site that support this protocol.
