Ocamlnet 4 Reference Manual : Nethttp_client.auth_handler

# Class type Nethttp_client.auth_handler

    class type auth_handler = object .. end

An authentication handler has the capability of adding the necessary headers to messages.

    method create_session : secure:bool ->
           http_call ->
           http_options Pervasives.ref ->
           auth_session option

Create a new authentication session. The passed call has status 401. The `secure` flag is set when the connection is secured by TLS.

    method create_proxy_session : http_call ->
           http_options Pervasives.ref ->
           auth_session option

Same for proxy authentication (status 407)

    method identify_session : http_call ->
           http_options Pervasives.ref ->
           (string * string * string * int) option

Extracts (mech_name,realm,sess_id,trans_id) if possible. Only needed for multi-step challenge/response authentication. THIS IS STILL EXPERIMENTAL.

    method identify_proxy_session : http_call ->
           http_options Pervasives.ref ->
           (string * string * string * int) option

Same for proxies. THIS IS STILL EXPERIMENTAL

    method skip_challenge : bool

If true, this method allows to skip the challenge entirely for authentication. This means that the credentials are added to the HTTP request before any previous response was seen from the server. This adds additional security risks, and may cause that credentials are sent to servers that forge their identity. This is only supported for basic authentication. As no challenge is known, the realm string is simply assumed to be "anywhere".

    method skip_challenge_session : http_call ->
           http_options Pervasives.ref ->
           auth_session option

Create a session for the case that the challenge was skipped
