Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps.

Let's check:

2.0.0-p481 :001 > OpenSSL::SSL::SSLContext::DEFAULT_PARAMS
 => {:ssl_version=>"SSLv23", :verify_mode=>1, :ciphers=>"ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM:+LOW", :options=>-2147482625}
2.0.0-p481 :002 > rating = JSON.parse(RestClient::Resource.new("https://www.howsmyssl.com/a/check" ).get)['rating']
 => "Bad"
