Abstract: Disclosed are various embodiments for generating a content page with markup language corresponding to user interface widgets. A user interface widget can generate markup language to be incorporated into the content page. The markup language can be analyzed to determine whether it contains a content identifier. The content identifier can be embedded within a portion of a URL. An analysis of the content identifier can be performed to determine whether the content identifier corresponds to expired content.
