#basic_authorize(user, password) ⇒ Object

  • PhantomJS with set settings doesn’t send ‘Authorize` on POST request

  • With manually set header PhantomJS makes next request with

‘Authorization: Basic Og==` header when settings are empty and the response was `401 Unauthorized` (which means Base64.encode64(’:‘)). Combining both methods to reach proper behavior.
