IMO CGI framework you proposed is not the same as the CGI protocol that
generally understood. Did you consider choosing another name like "webservice
framework"? This name is more fashionable and never be a misnomer because
webservices mean different thing to different people.

Currently CGI is re-implemented in every different ways
in-place in various J scripts and frameworks.
CGI is proposed to be implemented as a standard
general framework and addon to serve the needs
of all other related areas: Web Server, JHP,
special apps like Forums Search, other protocols
like FastCGI, etc.
Naming conventions:
Addons/web/cgi (addon location)
CGI/... (Wiki location)
CGI/Comments (area to continue this discussion)
What CGI framework will contain:
* external interface: command-line call and
configuration conventions
* boot script: for jconsole for general processing
of command-line params and environment variable
and discover and call application script
* handling environment variables and representing them
to J consumer scripts in common form, hiding
platform specifics, e.g. SCRIT_URL vs SCRIPT_NAME, etc.
* handling HTTP parameters in GET, POST and
multipart/form-data (for upload)
should include high-level "qparams" to extract
parameters (possibly typed) regardless of method
close to declarative form as in JHP;
also process structures, such as common prefix
as J locale with names, and same name params to list of
values, as from a set of checkboxes.
* maintain headers: declare content type, etc. like JHP
calculate content length
* support mime types and related headers
* provide output writer with encoding: binary or charset
like utf-8; buffered mode; hide Windows text mode stdout issue
* redirect to other URLs and execute other CGI scripts
* handle errors: try/catch; Respond.End() as special throw;
error reporting
* encoding/decoding utilities: url and HTML encoding
Basically it's CGI part of JHP split out and enhanced,
so that it is standard, general and flexible to handle
other applicationas and framework needs.
Doing so it makes sense how it is done in other languages,
notably Perl, PHP, python and ruby. It's good to make sure
nothing essential is missed and possibly borrow some
implementation.
Please see if I missed anything in the list above.
