my idea since the first designs of what is now Xavante is to make it easy to
write code to handle requests. the content managing is well served by CGIs
and server pages (and CGILua / .lp in Lua); the coding is the void i want to
fill. almost every time andre and i argue about how to do something, my
answer is "just write a handler"
in fact, i think only a few handlers should be generic and reusable; most
should be no more reused than the typical PHP code.
special-purpose code is cheaper; and as you go, you'll create your own library
of helper functions. (we're still missing a lot of these)

well, i've just coded cookies and session modules for Xavante, to be used from
handlers, without CGILua.
there's still no parameters parsing; but a simple :
for k,v in string.gfind (qry, "([^&=]*)=([^&=]*)")
gets you a long way

yep! that's very close to what i've been thinking about 'dispatching
and as for ".lp CGILua scripts" i've just added the capability to write
handlers using the same syntax as .lp note that these aren't CGILua .lp!
just a neat way to write xavante handlers
what else is coming?... two things: a framewark to write a full website as a
lua module (using require() and module()) and a coroutine-based procedural
framework, where a user session is handled as program flow...
