Hi I am sharing a demo product pdf file on my product page, but my product download link is not canonical although my product link is canonical.
demofiles.php
<tr>
<td class="descr"><?php print $demo->demo_descr?></td>
<?php if ($this->config->demo_type == 1) { ?>
<td class="download"><a target="_blank" href="<?php print $this->config->demo_product_live_path."/".$demo->demo;?>" onClick="popupWin = window.open('<?php print \JSHelper::SEFLink("index.php?option=com_jshopping&controller=product&task=showmedia&media_id=".$demo->id);?>', 'video', 'width=<?php print $this->config->video_product_width;?>,height=<?php print $this->config->video_product_height;?>,top=0,resizable=no,location=no'); popupWin.focus(); return false;"><img src = "<?php print $this->config->live_path.'images/play.gif'; ?>" alt = "play" title = "play"/></a></td>
<?php } else { ?>
<td class="download"><a target="_blank" href="<?php print $this->config->demo_product_live_path."/".$demo->demo;?>" rel="canonical"><?php print JText::_('JSHOP_DOWNLOAD')?></a></td>
<?php }?>
</tr>
