A redirection service directs, based on a received reference address and user identity information, a user to an appropriate version of a document or an application program. When the user is an author of the document, the user is directed to a version of the document that is undergoing revision. When the user is not an author of the document, the user is directed to a version of the document that is not undergoing revision. Similarly, when the user is a software developer, the user is directed to a version of an application program that is being developed; otherwise, the user is directed to a production version of the application program.
