To use HTML as an user interface device you need _only_ two _perfectly
defined_ things:

1. A HTTP server (with at least CGI capability)

2. A web browser (e.g. Netscape Navigator)

(Of course, a knowledge of the associated languages and conventions is also
necessary.)

To use a remote procedure call mechanism other than CGI, which is
operating system shell based, you may in fact want to tamper with the
server, or write one, and for that a working piece of source code would be
very helpfull.

But _that_ is exactly what is necessary---the source of an HTTP server, at
least one implementing a working fragment of HTTP 1.1---_and nothing else_.
Is (or has) any of these strange things---LynxOS, vxWorks, ETS---_the_
thing, i.e. a public Ada code version of a HTTP server?

Alternatively, and since the browser makes all the work converting and
editing the forms, one might want to tamper with the browser. Is there also
a browser in Ada?

Thanks.
