How to send a HEAD HTTP request in Python with urllib2

HEAD-request.py

import urllib2

class HeadRequest(urllib2.Request):
    def get_method(self):
        return "HEAD"

class HEADRedirectHandler(urllib2.HTTPRedirectHandler):
    """
    Subclass the HTTPRedirectHandler to make it use our 
    HeadRequest also on the redirected URL

    def redirect_request(self, req, fp, code, msg, headers, newurl): 
        if code in (301, 302, 303, 307):
            newurl = newurl.replace(' ', '%20') 
            return HeadRequest(newurl, 
                               headers=req.headers,

        else:

# Build our opener with the HEADRedirectHandler
opener = urllib2.OpenerDirector()

    opener.add_handler(handler())

response = opener.open(HeadRequest(url))

print response.geturl()
print response.info()
