Make a HEAD request. Here is one way of doing it, using urllib2.
class HeadRequest(urllib2.Request):
""" A request class which performs a HEAD request """
def get_method(self):
return 'HEAD'
req = HeadRequest(url)
f = urllib2.urlopen(req)
headers = dict(f.headers)
print headers.get('content-length',-1)
