Abstract: A content-aware routing method comprising the steps of: providing a Web sever cluster having a Web content for responding a plurality of requests via a network, wherein the sever content has a plurality of sever items each having a name with a variable-length alphabet string; providing a URL table having a plurality of record named with a fixed-length binary string converted form the variable-length alphabet string of the name of the sever items by means of a hash function; receiving a request packet with a object name via a network and retrieving the object name of the request packet; converting the retrieved object name into a retrieved fixed-length binary string by means of the hash function; and comparing the retrieved fixed-length binary string with the fixed-length binary string in the URL table for routing the request packet into the Web server cluster.

Abstract: A zero-loss web service system for providing World Wide Web access service to clients connecting via the Internet and sending requests to said system for said access, wherein the system comprises a server cluster and a dispatcher device. The server cluster comprises a number of servers connected in a network. The dispatcher device comprises a routing mechanism, the dispatcher dispatching each of the access requests sent by the clients to a corresponding one of the servers in the cluster, and the routing mechanism discriminating each of the requests sent by the clients and migrating the requests to another server in the event that the corresponding server suffers a service failure.
