RE: GUI, HTTP and LynxOS

In the absence of an Ada implementation of a complete HTTP server, you
should look at Amaya. It is free and available in source from the World Wide
Web Consortium www.W3.org (W3C Open Source Software). Also, you might look
at Jigsaw - The W3C's Web Server. It might be reasonable to create an Ada
binding to Amaya.  However, I have a very strong suspicion that an Ada web
server could be the killer application we need.

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.
