NormalizeURL will normalize the specified URL This was added to replace a previous call to the no longer maintained purell library: The call that was used looked like the following: url.Parse(purell.NormalizeURL(parsed, purell.FlagsSafe|purell.FlagRemoveDuplicateSlashes)) To explain all that was included in the call above, purell.FlagsSafe was really just the following: - FlagLowercaseScheme - FlagLowercaseHost - FlagRemoveDefaultPort - FlagRemoveDuplicateSlashes (and this was mixed in with the |) This also normalizes the URL into its urlencoded form by removing RawPath and RawFragment.
