I founded this code at WEBrick library:

class HTTPServer < ::WEBrick::GenericServer
def initialize(config=3D{}, default=3DConfig::HTTP)
super


What kind of inheritance is HTTPServer << ::WEBrick, I don't undestand de :=
:
before. What does it means?

It's there to make sure the right class is used. Try:

class A
def foo
"a"
end
end

module B
class A
def foo
"ba"
end
end

p A.new.foo
p ::A.new.foo
end

"ba"
"a"
=> nil
