Far easier would be grabbing the URL's and then using
urlparse.urlparse() on them. Relative paths should be combined with the
base scheme://location/path. When you want to see if they are on your
host, just use .startswith(). If you're worried about ../, make the
paths concrete (os paths) and call os.path.normpath before comparing
them.
