Show all products in a page + rel=canonical

[broc93]

Hello.
I wanted to put on my website a page with all the products ordered from the most sold to the least. I thought it would be a good idea just to use a link like this one: http://www.prodotti-herblife-vendita-online.it/orderDesc/by,product_sales

The fact is, this page has a

Code Select Expand

<link href="/" rel="canonical"/>, which means that crawlers read it as equivalent to the homepage. Also breadcrumbs show me that I'm in homepage, and I don't want to.

The problem is that Google also sees pages like "/orderDesc/by,product_sales/results,1-12", "/orderDesc/by,product_sales/results,1-6", "/orderDesc/by,product_sales/results,1-3" which are automatically created with a rel="canonical" attribute to the homepage.

How could I solve this problem?
Shall I put all the products in a single category called "All products", but then, how can I make "number of sales" the default order (without changing that of the other categories)
Otherwise, what shall I do?

Thank you very much in advance, hope someone could help me.
Have a nice day!

check what is happening in components/com_virtuemart/views/category/view.html.php

public function setCanonicalLink($tpl,$document,$categoryId,$manId){
      // Set Canonic link
      if (!empty($tpl)) {
         $format = $tpl;
      } else {
         $format = JRequest::getWord('format', 'html');
      }
      if ($format == 'html') {

         $link = 'index.php?option=com_virtuemart&view=category';
         if($categoryId!==-1){
            $link .= '&virtuemart_category_id='.$categoryId;
         }
         if($manId!==-1){
            $link .= '&virtuemart_manufacturer_id='.$manId;
         }

         $document->addHeadLink( JRoute::_($link, FALSE) , 'canonical', 'rel', '' );

      }
   }

perhaps add another 'if' for special page
