title: How to say to server I can parse Javascript in Perl Mojo::UserAgent?
body: <p>I try to use <code>Perl</code> <code>Mojo::UserAgent</code> to crawle a website, but the server checking the browser's Javascript support capability. It is possible to say / lie my client support Javascript?</p>
  
  <p>Now I have only this code:</p>
  
  <pre><code>use Mojo::DOM;
  use Mojo::UserAgent;
  
  my $ua = Mojo::UserAgent-&gt;new;
  $ua = $ua-&gt;transactor(Mojo::UserAgent::Transactor-&gt;new);
  $ua-&gt;transactor-&gt;name('Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0');
  my $tx = $ua-&gt;post("http://..." =&gt; form =&gt; {
                      "login_username" =&gt; "...",
                      "login_password" =&gt; "..."
              });
  </code></pre>
  
  <p>It is possible to do? If not possible, is there exists any other perl-based user-agent what can do this?</p>
