Status 301 Moved Permanently


As a customer I'm trying to see the balance of a coupon through the link /index.php?dispatch=gift_certificates.verify&verify_code=code but the server returns the status code “[color=#808080][font=Consolas,]301 Moved Permanently (from cache)[/font][/color]”. Why is it happening?

I've got two domains, one of them I can use the feature normally, but not in the other one.
