How to login to ASP.net page through apache HTTPClient

[fordint]

Hi,

I am trying to login to https://alta.registries.gov.ab.ca/SpinII/Logon.aspx. But I couldn't be successfull. This site use https protocol for login page and after login redirect to http protocol page. Can any body help me? Following is the code. I don't know, where am I making mistake. It is using basic authentication.
