Python Forum

Please help. I'm trying to create a POST request on an .asp site that requires cookies, but the way I handle them seems not to return anything. Read through some questions of similar topic but can't find the _SessionID cookie some are referring to. Please help me formulate this POST request so it works.

MY CODE SO FAR:

    response = s.get(url, headers=headers, data=data, params=params)

    if response:

    else:

On line 27 you send GET not POST
