I tried:

require "open-uri"
trg= open
"https://www.knightonlineworld.com/index.php?pg=rankings&sub=2&radServer=1&clanid=12199"

trg.each do |line|
	puts line
	end

Result:
c:/ruby/lib/ruby/1.8/open-uri.rb:583:in `proxy_open': open-uri doesn't
support https. (ArgumentError)
	from c:/ruby/lib/ruby/1.8/open-uri.rb:525:in `direct_open'
