I finally got it to work with not too much code (most of it given by
Ignacio) but some time wasted. Here is the final webserver code of my
application :

local function custom_sapi_loader(wsapi_env)
	wsapi.common.normalize_paths(wsapi_env)
	
	_G.CGILUA_ISDIRECT = true
	_G.CGILUA_CONF = "."
	_G.CGILUA_TMP = "."
	
	local app = require "wsapi.sapi"
	local status, headers, iterator = app.run(wsapi_env)
	-- it is necessary to reload Cgilua packages and wsapi.sapi. it has
way too much dependency on global
	-- environment
	package.loaded["cgilua"] = nil
	cgilua.SAPI = nil
	package.loaded["wsapi.sapi"] = nil
	
	return status, headers, iterator
end

local webdir = ".\\"
xavante.HTTP{
	server = {host = "*", port = web_port},
	
	defaultHost = {
		rules = {
			{
				match = "^[^%./]*/$",
				with = xavante.redirecthandler,
				params = {"index.lp"},
			},
			{
				match = "%.lp$",
				with = wsapi.xavante.makeHandler(custom_sapi_loader, nil, webdir, webdir),
			},
			{
				match = ".",
				with = xavante.filehandler,
				params = {baseDir = webdir}
			},
		},
	},
}

I then run my coroutine-based, copas-like event loop. It would be nice
to add in-interpreter processing of LuaPages to Xavante, or to put an
example like the code above in a very visible place.
