determine-username/password #!optional HANDLERparameter

The procedure in this parameter is called whenever the remote host requests authentication via a 401 Unauthorized response.

The HANDLER is a procedure of two arguments; the URI for the resource currently being requested and the realm (a string) which wants credentials. The procedure should return two string values: the username and the password to use for authentication.

The default value is a procedure which extracts the username and password components from the URI.

For proxy authentication support, see determine-proxy-username/password in the next section.
