There's also the Addressable Gem: <http://Addressable.RubyForge.Org/>.

It's intended as a standards compliant replacement for the stdlib's
URI library. Take a look into the test directory of that sucker: over
440 Unit Tests (actually, Object Examples) for a frickin' URI parser!
(See: <http://Addressable.RubyForge.Org/specdoc/>) That guy is nuts!
That code's gotta be as rock-solid as it gets.

Oh, and back to the topic at hand: it has a normalize method built in:

	begin
	  require 'rubygems'
	  gem 'addressable'
	rescue LoadError; end
	require 'addressable/uri'
	uri = Addressable::URI.heuristic_parse('www.Ruby-Lang..ORG/ARSE/done/../../r e a r/./end/.#exit')
	uri.normalize!
	puts uri.display_uri # => http://www.ruby-lang..org/r%20e%20a%20r/end/#exit
