For example:
require 'net/http'
uri = URI('http://example.com/some_path?query=string')
Net::HTTP.start(uri.host, uri.port) do |http|
request = Net::HTTP::Get.new uri
response = http.request request # Net::HTTPResponse object
end
What is the correct/rubist way to get rid of Net::HTTP ? i.e. HTTP::Get.new() or just Get.new()

The namespace in Ruby is defined by prefixing the keyword module in front of the namespace name. The name of namespaces and classes always start from a capital letter. You can access the sub members of double with the help of :: operator.
As with class methods, you call a module method by preceding its name with the module's name and a period, and you reference a constant using the module name and two colons.
You can define and access instance variables within a module's instance methods, but you can't actually instantiate a module.
include is the most used and the simplest way of importing module code. When calling it in a class definition, Ruby will insert the module into the ancestors chain of the class, just after its superclass.
If you want to shorten these, you can just import that namespace:
Net::HTTP.start(...)
include Net
# HTTP.start(...)
Be careful when you import aggressively as it might cause conflict within your class if you get carried away.
An alternative is to create aliases:
HTTP = Net::HTTP
Get = Net::HTTP::Get
The "correct" way is to just spell it out and not get too flustered by that. A typical Ruby program will bury this sort of low-level behavior beneath an abstraction layer so it's rarely a big deal.
