title: Why netbeans is trying to connect to a debug proxy?
body: <p>I'm trying to setup netbeans 7.3 with xdebug 2.2.1 on a Debian wheezy. I'm trying to make it work on a localhost-basis, it is, only one xdebug user connecting from the same machine (the most common configuration). After some hours I have this:</p>
  
  <ul>
  <li><strong>Xdebug is working</strong>: I execute the <code>debugclient</code> included with the Xdebug sources and it works (i.e. when I type in the Chrome address bar <code>http://localhost/file.php?XDEBUG_SESSION_START=netbeans-xdebug</code> the <code>debugclient</code> receives a XML response and I can interact with it sending the appropiate commands.</li>
  <li><strong>Other debug clients can connect</strong>: I have checked that it works with Sublime Text 2 (but ST2 is not an option to substitute netbeans by the moment).</li>
  <li><strong>Netbeans is blocking when using the debugger</strong>: If I press F6 (<em>Run the project</em>) the projet main page is launched on Chrome, but if I press CTRL+F5 (<em>Debug project</em>) a "<em>Waiting for connection (netbeans-xdebug)</em>" message appears and the project main page is not launched in Chrome <strong>until</strong> I press on <em>Finish debug session</em>. Then the page is launched but without debugging support, obviously.</li>
  <li><strong>Netbeans seems to be trying to connect to a debug proxy</strong>: I have captured the port 9000 packets and when the other debuggers (<code>debugclient</code> and <code>ST2 plugin</code>) send XML formatted requests, <code>netbeans</code> receives a weird <code>proxyinit -p 9000 -k netbeans-xdebug -m 0</code> string. <a href="http://xdebug.org/docs-dbgp.php#just-in-time-debugging-and-debugger-proxies" rel="nofollow noreferrer">Proxyinit</a> seems to be an informative request in order to setup multiuser system (but I only need a user).</li>
  </ul>
  
  <p>This is the capture when using <code>debugclient</code></p>

  <p>and that's the same when using <code>netbeans</code></p>

  <p>I'm a bit confused because it is supposed that the XML message is sent by xdebug agnostically, it is, without any information about who is waiting to receive this message... </p>
  
  <p>So the question is: why netbeans or xdebug (I don't know who) is trying to connect to a debug proxy?</p>
