title: switch store without GET Parameter in Magento
body: <p>I would like to make an invisible redirection from a store to a different one (I set up multistore)
  into my module, for now I'm using this snippet but it shows GET parameter:</p>
  
  <pre><code>echo '&lt;p&gt;&lt;a href="' . Mage::getUrl() . '?___store=' . $store . '"&gt;pick up this restaurant&lt;/a&gt;&lt;/p&gt;'
  </code></pre>
  
  <p>How can I achieve this ?</p>
  
  <p>Thx</p>
