- send_auth_header(+AuthData, +Out, +Options)
- Called when sending the initial request. AuthData contains
the value for the http_open/3
authorization(AuthData)and Out is a stream on which to write additional HTTP headers.
- auth_reponse(+Headers, +OptionsIn, -Options)
- Called if the server replies with a 401 code, challenging the client.
Our implementation adds a
request_header(authorization=Digest)header to Options, causing http_open/3 to retry the request with the additional option.
