Returns the given request's URL, properly encoded for use with urllib.
We expect that the given request object already verified that the URL

a bytes object using an explicitly specified ASCII encoding.
Python 2.7 httplib implementation expects the URL passed to it to not
be a unicode string. If it is, then passing it to the underlying
httplib Request object will cause that object to forcefully convert all
of its data to unicode, assuming that data contains ASCII data only and
raising a UnicodeDecodeError exception if it does not (caused by simple
unicode + string concatenation).
Python 2.4 httplib implementation does not really care about this as it
does not use the internal optimization present in the Python 2.7
