Returns the full path for this URL, without
decoding percent-escapes. This is useful if
you need to distinguish between "/" and "%2F" in the
path. The normal
-path
method will convert all "%2F" value in the path into
"/" so that you have no way of knowing whether a "/" is
part of a path component ir is a path separator.
Returns a string (encapsulating the scheme, host
and port of the receiver) suitable for use as a key to
store the receiver in a cache of objects used to
access resources using the same network connection.
