title: Phabricator rewrite rules configuring issue
body: <p>I'm having trouble installing phabricator. It actually seems like it would be a simple thing. I copied the example code exactly. </p>
  
  <p>apache2.conf:</p>
  
  <pre><code>&lt;VirtualHost *&gt;
    # Change this to the domain which points to your host.
    ServerName localhost
  
    # Change this to the path where you put 'phabricator' when you checked it
    # out from GitHub when following the Installation Guide.
    #
    # Make sure you include "/webroot" at the end!
    DocumentRoot /var/www/phabricator/webroot
  
    RewriteEngine on
    RewriteRule ^/rsrc/(.*)     -                       [L,QSA]
    RewriteRule ^/favicon.ico   -                       [L,QSA]
    RewriteRule ^(.*)$          /index.php?__path__=$1  [B,L,QSA]
  &lt;/VirtualHost&gt;
  
  
  &lt;Directory "/var/www/phabricator/webroot"&gt;
    Require all granted
  &lt;/Directory&gt;
  </code></pre>
  
  <p>Whenever I go to the server IP on a browser, it gives me this error: </p>
  
  <pre><code>Request parameter '__path__' is not set. Your rewrite rules are not configured correctly.
  </code></pre>
  
  <p>I found that this was part of the phabricator code:</p>
  
  <pre><code>if (!isset($_REQUEST['__path__'])) {
      self::didFatal(
          "Request parameter '__path__' is not set. Your rewrite rules ".
          "are not configured correctly.");
  }
  </code></pre>
  
  <p>Anyone have any idea how to get past this?</p>
