mod_rewrite with product_sku instead of product_id

[lazy]

Hi,

i'am familiar with PHP programming but new to VM. I've searched the forum but didn't found a solution for my problem.

normally the link is as follow:

Code: [Select]

index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=369&virtuemart_category_id=52&Itemid=160
how can i call the shop with product_sku? like this

Code: [Select]

index.php?option=com_virtuemart&view=productdetails&virtuemart_product_sku=119283
