title: Magento ignores extra URL parameters set
body: <p>I am trying to open a Magento store link from an external site. While opening the store link I need to send some information using the query string parameters. 
  So I open a link (through php code) such as: 
  <a href="http://magentostore.com/myproduct.html?id=3434&amp;user=445" rel="nofollow">http://magentostore.com/myproduct.html?id=3434&amp;user=445</a></p>
  
  <p>However the Magento store link ignores the query string parameters and reloads the page as:
  magentostore.com/myproduct.html</p>
  
  <p>I checked in Firebug and can see that there was a redirect to the Magento store without the query string parameters. Is there a way to override this behavior and let Magento load with the query string parameters?
  What setting can I do in the Magento store to let it allow using the query string parameters?
  Is there any other way of sending some more information to the Magento store page? </p>
  
  <p>Is there a way to find out if its Magento doing this and not the server?</p>
  
  <p>Thanks</p>
