I have a script that writes the http address to a link according to the sku number of a product. That link is supposed to be directed to a website that shows a picture of that product with a little description. But some products dont have pictures or a description and the link gets written anyway. Then when the user clicks it, they get a 404. So I was wondering if it is possible to have the script check to see if the page doesnt return a 404 then write the link to the page and if it does return a 404 then I do not want the link posted. Can that be done?
