title: htaccess - Displaying same page through different URLs with URI passed to controllers
body: <p>I'm trying to have the same page display on different URLs. For example <code>www.example.com</code> will display either I access it from <code>www.example.com/city1</code> or <code>www.example.com/city2</code> without changing the url.</p>
  
  <p>What I did is to use the below code in my <code>.htaccess</code>:</p>
  
  <pre><code>RewriteRule ^city1 / [P]
  RewriteRule ^city2 / [P]
  </code></pre>
  
  <p>This seems to work and indeed by accessing the /city1 or /city2 I get pointed to the homepage with keeping my url intact. However this seems to not pass the URI to my controllers. This is mandatory for my business logic as the whole App depends on the <code>/city1</code> or <code>/city2</code> to decide what content should be displayed.</p>
  
  <p>I think small tweak to the rewrite should do it, but I can't figure out how.</p>
  
  <p>.htaccess:</p>
