There is a feature in Internet Explorer's cookie handling preferences that causes Internet Explorer to prompt you for each new cookie that is being saved. The preferences in question let you allow or deny each cookie, domain-by-domain and get IE to remember the setting for each domain.
Is there an extension for safari that will emulate this behaviour?
