Excellent! I really should look into Sajax, too.

Of course the ease of writing helpers / special-purpose-code depends
significantly on having a rich API from the httpd / cgi core.

Hmm. I'm surprised. Why not refactor CGILua to expose more of its
functionality in its API and use that within Xavante? Why rewrite
code that's already available?

Well it's a start but then CGILua already goes much further and
handles multipart forms including file uploads. Again, why not
refactor CGILua's API rather than duplicate the code?

Meaning that such a xavante handler can include parameter substitution
(<%= cgi.mytextinput %>)? I don't understand. (Is this new code in

So xavante is evolving from a web server with built-in cgi scripting
support towards a web applications framework? That sounds very
