ABSTRACT:
In a system where a central load distribution server at a publicized URL redirects requests for files to a number of content servers holding identical content on the basis of dynamically determined capacity utilization of those servers, clients are prevented from directly accessing one of the content servers without first being redirected from the central load distribution server. In the event that a client attempts to access one of the content servers without first having been redirected there from the load distribution server, the client is redirected to a page containing a notice of the error, then redirected yet again to the load distribution server. For browsers in which bookmark lists may be edited by the user, facilities are provided for correcting the bookmark entry that brought the user to the protected content server rather than to the central load distribution server. In this way, the tendency of users to unintentionally or intentionally circumvent traffic routing algorithms is substantially reduced and the risk of any one content server being overwhelmed with traffic is likewise reduced.
