Problem with @ in URL

[fjcero]

Hi! I have the next path in a Angular application:

.state('signup', { url: '/signup/invite/{code:[0-9a-fA-F]{64}}?email&name' });

The thing is to access this using HTML5 mode I added the next config (the same as everyone in the internet) to Grunt to serve the application with modrewrite:

  var modRewrite = require('connect-modrewrite');
  var serveStatic = require('serve-static');
  connect: {
    ...
    middleware: function (connect, options) {
      var middlewares = [];
      middlewares.push(modRewrite(['!(\\..+)$ / [L]']));
      options.base.forEach(function(base) {
        middlewares.push(connect().use(serveStatic(base)));
      });
      return middlewares;
    }
    ...
  }

But then, when I have a URL like: http://localhost:9000/signup/invite/72fa78cbe19327a61cc0ea992f0e341f8cb78266cd248df6cd6650341cf5d4b8?email=example@example.com&name=Its+me+Mario the redirection fails. At first I though it was something in the configuration, but then I started playing with the query string params until I removed the @ and everything goes well.

So, the question is, how could I trace this error and understand better how modrewrite is handling this cases, to fixit or to avoid it.

Closing until I perform some other tests, but if there is a way to debug modrewrite faster, I will appreciate it :)
