URL normalization :- http://en.wikipedia.org/wiki/URL_normalization - I
just read this source.

I found a method uri#normalization :
http://www.ruby-doc.org/stdlib-2.0/libdoc/uri/rdoc/URI/Generic.html#method-i-normalize-21

But not able to figure out how this method works:

require 'uri'

uri = URI.parse("http://www.example.com/../a/b/../c/./d.html";)
p uri.normalize.to_s
#=> "http://www.example.com/../a/b/../c/./d.html";
But I expect " http://www.example.com/a/c/d.html";

Nothing any thing change encountered. So any one out there have any good
example to understand this method?

Thanks
