Since I am not yet using this library I will limit my observation to the
fact that the scheme (https:) and the host (//www.dotster.com) are normally
implied by a) the connection port (443 by default) and b) the connected
host. I would therefore have expected the first line to be

send: 'POST /account/login/login.asp HTTP/1.1\r\n'

but I don't know if this is what's causing your problem.
