With rewrited parameter (vers 0,0,10), the « tx_metaoscommerce_pi1[oscommerceURL] » parameter now contains a shortMD5 of URL. So it can now easily be rewrited by RealUrl

You can use this parameter (in your RealUrl conf)

« cat » text is just for example.

'postVarSets' => array(

            '_DEFAULT' => array(

'cat'=>array(

array(

'GETvar' => 'tx_metaoscommerce_pi1[oscommerceURL]',

),

),

                ),            

            ),

URL will look like :

/en/shop/cat/50acd236ae.html

rather than

/en/shop.html?tx_metaoscommerce_pi1[oscommerceURL]=.......
