req = http.get('/test.txt')

You have to use the http connection to make the GET request.

Do you have a firewall or proxy between your PC and the internet? I
remember that I had a problem like this (years ago). Just a wild guess.

It works for me, as written, and I'm using ruby 1.8.6. I believe the API for net/http changed a little between versions. I don't remember the exact change, but try this variation:

require 'net/http'
Net::HTTP.start('www.rubyinside.com') do |http|
         res = http.get('/test.txt')
         puts res.body
end

Also try ".get2" instead of ".get". Good luck.

I've run your code on Ruby 1.8.6 on OS X, so this could either be a net/http issue in 1.8.4, or a Windows issue, or a net/http issue with Windows. Sorry I can't verify further.

If nobody can reply that knows how to do this with ruby-1.8.5, then the easiest thing would be to upgrade your installation of ruby. I can't say for sure (because I'm not running Windows), but the script should work with no modification in ruby-1.8.6. You should probably use the one click installer, available at http://rubyforge.org/frs/download.php/27227/ruby186-26_rc2.exe .

Good luck,
