Python detecting user login redirection slow

Question

I am trying to detect whether logging into a web form creates a redirection or not. Right now this process is fairly slow:

import urllib, urllib2

def redirection_occurs(user, password, login_page_url ):

    login_data = urllib.urlencode({
        'username':user,
        'password':password
    })

    data = urllib2.urlopen( login_page_url, login_data )

    # Returns true if redirection occurs
    return data.geturl() != login_page_url

What makes the whole thing slow is the call to urllib2.urlopen( login_page_url, login_data ), is there a way around this? I simply want to detect whether or not a redirection has occurred after a login.

Is this server code using bottle, flask, tornado, etc -- whats the context? — Gabe Rainbow, Apr 19 '15 at 01:39
No it's a simply a python script using urllib and urllib2 modules. I added them as imports in the code I provided. — will.fiset, Apr 19 '15 at 01:46

this seems to be largely answered here although not a perfect repeat question.

nevertheless, use a heads request

in python requests its

requests.head(url, **kwargs)

instead of

requests.request(method, url, **kwargs)

Using the urllib2 library use the answers from this SO question

If you were to put this inside a method to check for redirection, how would you do it? – will.fiset Apr 19 '15 at 02:26
checking the status for 300 code as in the requests example str(response.status).startswith("3"): – Gabe Rainbow Apr 20 '15 at 20:41
