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.
