Reads the file contents from a URL. I used this code to work around the problem with the Ruby RSS reader which couldn't read the RSS file from digg.com. The reason being that the website would not allow files to be downloaded without supplying the User-Agent string.
require 'open-uri' puts open('http://digg.com/rss/index.xml', 'User-Agent' => 'Ruby-Wget').read
