POST request with form data issue web scraping

[hoff1022]

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.
