magento - Redirect a product to other website -

i looking way have product on magento store, make visible not purchaseable , redirect users accessing page/external url. have 6 products , redirect users go 1 of products domain / external url. product should displayed not purchaseable - rather instead of add cart link external url - or if possible redirect whole product detail page url...

what’d best way that?

i trying 2 days haven’t found best solution yet… programming skills aren't best yet...

thanks!

i think should add 1 new attribute redirect url , 6 products can specify redirect url in attribute , , in list.phtml can place condition if product has value in attribute , can use value in anchor tag , in else case cam use regular product links other products .
