Hello there guys,

I'm trying to track down an easy way to canonicalize a URL from with
ruby. I've been looking around for this but all I can find are some
procedure hacks sure as  # canonicalize the url
    if ($url -notmatch "^[a-z]+://") { $url = "http://$url" }

which isn't going to take into account everything according to RFC 2396

    *   Remove all leading and trailing dots
    * Replace consecutive dots with a single dot.
    * If the hostname can be parsed as an IP address, it should be
normalized to 4 dot-separated decimal values. The client should handle
any legal IP address encoding, including octal, hex, and fewer than 4
components.
    * Lowercase the whole string.


#  The sequences "/../" and "/./" in the path should be resolved, by
replacing "/./" with "/", and removing "/../" along with the preceding
path component.
# Runs of consecutive slashes should be replaced with a single slash
character.

So is there a method out there for this?
