I have used Net::HTTP like this: Net::HTTP.get ‘[google.com](http://google.com)’, ‘/index.html’ I would like to pass it a variable instead. I tried this: irb(main):001:0\> require ‘net/http’ =\> true irb(main):002:0\> url = String.new =\> “” irb(main):003:0\> url = “‘[google.com](http://google.com)’, ‘/index.html’” =\> “‘[google.com](http://google.com)’, ‘/index.html’” irb(main):004:0\> Net::HTTP.get\_print(url) NoMethodError: undefined method `host' for "'google.com', '/index.html'":String from /usr/lib/ruby/1.8/net/http.rb:379:in `get\_response’ from /usr/lib/ruby/1.8/net/http.rb:337:in `get\_print’ from (irb):4 from :0 How do I pass a variable to Net:HTTP ? ---

Thanks for the tip Jesus. I used to program in C so I have some bad habits. I just tried my code without creating all those objects and everything went fine. ---
