For me the real reason why we don't want to specify an API for this is that API's are the client/server way of doing things and protocols are the Web way of doing things - i.e. let's keep it consistent.

We should however specify and API whereby the access control can be provided by a third party application (server extension) on the server side thereby relieving the server providers from the necessity of providing the functionality (they only have to support the API).

Cheers
Dylan

The reason an API based approached was initially suggested was
to provide a mechanism through which server-based applications
which act as "receivers" for requests from the client could have
a standardized mechanism for asking the environment whether the
user has a particular permission.

There are some precedents within the IETF/RFC community for APIs,
namely GSS-API (A security API, not related specifically to
permissions).

The CGI standard effectively implements an API by defining
environment variables as a mechanism for passing information
between the server and forked processes.

In addition, it might be possible to develop an API that is
language neutral by using a technology such as CORBA.  The
principal drawback there is the lack of extensive CORBA
deployment and the additional overhead associated with using
it.

Permissions are essentially a "server" technology.  It is unclear
to me what information regarding permissions would ever be
transacted between the client and the Web server, other than
perhaps a denial-of-access response (which is already handled
in the HTTP 1.0 spec).  In addition, the predominant leaning so
far from everyone has been that a spec that governs the creation
and management of permissions is out of scope.  That leaves us with
the issue of resolving what a particular user can or can't do.

Any comments on the above?
