The invention relates to a network load equalizing method in a basis of SSL digital certificate, comprising steps of: 1) Defining a plurality of background server groups; 2) Solving a key value according to content of SSL digital certificate in the client requests when the client requests are received; 3) finding corresponding background server groups according to solved key value; 4) Distributing the client requests to found background server groups. The method pays attention to computer network security while equalizing the load, which not only guarantees security of network affaire process, but also enables the client served to obtain rapid response. The invention uses capacity of the background server groups maximally. Each server group provides service for requests from different clients. Each server groups processes different client requests, which enables the client served to obtain rapid response.
