title: i18n_patterns: How come some user are accessing /en-us/ where what I have is /en/
body: <p>I am using i18n_patterns for my URL and yesterday when I launched the live site I noticed through Google Analytics many people are accessing <a href="http://www.example.com/**en-us**/" rel="nofollow noreferrer">http://www.example.com/**en-us**/</a> instead of <a href="http://www.example.com/**en**/" rel="nofollow noreferrer">http://www.example.com/**en**/</a>. I do not have <a href="http://www.example.com/**en-us**/" rel="nofollow noreferrer">http://www.example.com/**en-us**/</a> link anywhere on my site.</p>
  <p>Personally, when I try to access the site through <a href="http://www.example.com/" rel="nofollow noreferrer">http://www.example.com/</a> I am redirected to <a href="http://www.example.com/**en**/" rel="nofollow noreferrer">http://www.example.com/**en**/</a> which is the wanted behaviour. Also when I try <a href="http://www.example.com/**en-us**/" rel="nofollow noreferrer">http://www.example.com/**en-us**/</a> I get a not found page, which is also what I want, since it's not good for SEO to have multiple URls for the same page.</p>
  <p>Now the weird is I am actually seeing visitors at /<strong>en-us</strong>/ because I do not have Google Analytics on the not found page yet!</p>
  <p>This is part of my settings:</p>
  <pre><code>LANGUAGE_CODE = 'en-us'
  
  gettext = lambda s: s
  LANGUAGES = (
      ('en', gettext('English')),
      ('fr', gettext('French')),
      ('es', gettext('Spanish')),
  </code></pre>
  <p>Any idea what is causing that? Are these people getting a not found page, and how can I eliminate the issue? It's really hard to debug it when it is not happening to me!</p>
