Did You mean this code in Web.hx (haxe
v.2.05 /usr/share/haxe/neko/Web.hx lines 348-356)?
==========================
} else {
var a0 = untyped __dollar__loader.args[0];
if( a0 != null ) a0 = new String(a0);
_set_main = function(f) { };
_get_host_name = function() { return untyped
"localhost".__s; }; _get_client_ip = function() { return untyped
"127.0.0.1".__s; }; _get_uri = function() {
return untyped (if( a0 == null ) "/"
else a0).__s; };
==========================
I can't see a params parse code here but it seems to work for
nekoserver and not to work with lighttpd. (I mean GET).
Printing environment variables:
New code:
class Gettest {
public static function main()
{
neko.Lib.print(neko.Sys.environment());
neko.Lib.print("\n\n");
trace(neko.Web.getParamsString());
}
}

-----------------------
What do we see here? LIGHTTPD PUSHES GET_PARAMS TO NEKO!!! COOL! But
seems that it does it in other way than nekotools server. So, I could
parse the HTTP headers myself, but getParamsString() doesn't work.
It's about GET: it works normally in nekotools server but it doesn't
work neither in lighttpd nor in iis.
POST protocol I will check later today or tomorrow and sureley will send
results.
