[cgi-devel] truncated post variable

[<jc...@ol...>]

Hello Darren,

I am struggling with the following issue. On a linux box with nginx as the
webserver

on the client's side, I am making the following jquery call:

function sign_up()
{
  $("#sign_up_feedback").html('').hide();
		$.post
		( "/",
				{ task: 'sign_up',
				  member_username: $('#member_username').val(),
				  member_password: $('#member_password').val(),
				  member_password_repeat: $('#member_password_repeat').val(),
				  member_first_name: $('#member_first_name').val(),
				  member_last_name: $('#member_last_name').val(),
				  member_phone: $('#member_phone').val(),
				  member_email: $('#member_email').val(),
				  member_corporation_id: $('#member_corporation_id').val(),
				  member_unit: $('#member_unit').val(),
				  member_card_number: $('#member_card_number').val(),
				  member_card_expiration: $('#member_card_expiration').val()
				},
				function(data)
				{
				  $("#sign_up_feedback").html(data).show();
				}
  );
}

I have used similar functions, thousands of times but, this time,when I
read the post values server side
using
print_variables_(req.post, "POST");
with
template<typename Map>
void
print_variables_(Map& m, std::string title)
{
  std::ostringstream os;
  os << title <<  "\n";
  if (m.empty())
  {
    os << "NONE\n";
  }
  else
  {
    for(typename Map::const_iterator i = m.begin(); i != m.end(); ++i)
    {
      os << i->first << " = " << i->second << "\n";
    }
  }
  os << "\n";
  write_to_file("~/log_requests", os.str());
}

member_card_number is truncated to member_card!  I looked at the http
headers and the nginx logs and member_card_number is not truncated.
I am very puzzled here as this has never really happened to me.
Where in the source code of the CGI library could I see where the parsing
of the http header is done?

Thank you very much
Jean-Christophe
