title: Magento shop language switch
body: <p>I have a magento shop with 2 languages. The language switcher works with set a different store view in the url.</p>
  
  <ul>
  <li><code>/shop/?___store=myshop_view</code> for mainlanguage</li>
  <li><code>/shop/?___store=myshop_view_fr</code> for french</li>
  </ul>
  
  <p>That works fine and how it should work.
  Now first problem comes when I am in french store and switch to mainlanguage with <code>/shop/?___store=myshop_view</code>, now I see the shop in the mainlanguage, but when I call <code>/shop/</code> without any storeview paramenters it switches back to french. Why is that and can I change that?</p>
  
  <p>The second problem comes with externall add to card links. A add to card link would look like: <code>/shop/checkout/cart/add/uenc/aHR0cDovL3d3dy5teS13aW5lLmNoLnJ1dGlzaGF1c2VyLm5pbmUuY2gv/product/2169/?___SID=U&amp;___store=myshop_view</code>
  So this link is for the main language. If the shop was in french before and I click this link, i get the success message in the main language, but the rest of the shop is french again.</p>
  
  <p>I think the first and second problem are nearly the same. Then the add to card link will redirect to the shop overview without any store view paramenter in the url.</p>
  
  <p>Any idea how I can get a add to card link that can switch the language of the shop?</p>
