Network session storage method, and network access method and device

The invention provides a network session storage method, and a network access method and device. The network session storage method comprises the following steps: after logging in a network from a client side, acquiring conversation content corresponding to session data generated at the client side; creating cookie data corresponding to the client side, and storing the session content into the cookie data; returning the cookie data to the client side, so that accessing network from the client side, a network server can restore corresponding session data through the cookie data sent by the client side. According to the network session storage method, and the network access method and device, the workload of the network server can be lightened, and the influence of the network server on the response speed of the client side can be reduced.
