Neko dev server crashing

Hello all,

  We're experiencing a strange issue with Neko dev server
here: on a
  specific machine it crashes when processing a request from
Firefox.
  Same requests done with IE/Opera work pretty fine. The
exception
  we're getting is:

  Starting Neko Server on localhost:2000
  Called from tools/Tools.nml line 40
  Called from core/Args.nml line 43
  Called from core/Args.nml line 50
  Called from tools/Tools.nml line 31
  Called from core/Net.nml line 96
  Called from core/Array.nml line 100
  Called from core/Net.nml line 102
  Called from tools/WebServer.nml line 565
  Called from tools/WebServer.nml line 566
  Called from tools/WebServer.nml line 522
  Called from tools/WebServer.nml line 174
  Called from core/Lexer.nml line 214
  Called from tools/WebServer.nml line 107
  Called from core/Core.nml line 197
  Exception : Invalid_char

  The question is how do I debug that? The line that crashes
from
  WebServer.nml is
        var meth = Lexer.token l http_request_method;
  I'd like some kind of trace() to be put into NekoML code
to see
  what's exactly wrong with the request..

Best regards,
 Michael                          mailto:mikecomapping.com

Hi,

It seems like some part of the HTTP protocol cannot be
understand by the
webserver.

What you can do is the following :

before "Lexer.input" in parse_http_request, add
the following lines :

var str = IO.read_all in;
printf "=====%s=====" str;
var in = IO.read_string str;

This will should all HTTP requests before parsing them.
Please send me the output of the HTTP requests that fails,
or try to
understand why it fails by checking the grammar rules (see
Lexer.build
calls in Webserver.nml)

Best,
Nicolas
