Concurrency issue in Web Application

I have certain number of links in a page and the user can delete those links. If two users enter at a time, both can see the same number of links. But now if one user deletes one of the hyper-links and then the other user clicks on the same hyper-link, i encounter page cannot be displayed error. This is because the details will be deleted from the database when the first user deletes that link and so the second user cannot get the details from the database.

Requirement: If the link is deleted in one page by one user, then pages of other users should be refreshed so that the user will not be able to see the deleted hyperlinks. Please suggest !!!!
