According to the session data, the cache identifier is generated, so that the session request can be received next time, and when the first application server fails, other application servers can quickly acquire the cache device where the session data is located according to the cache identifier, and quickly acquire the corresponding session data, so that the efficiency of processing the session data is improved. It should be noted that the cache identifier includes a device identifier corresponding to the first cache device and a Session identifier corresponding to the Session data, and a format of the cache identifier is < Session ID > + < Redis ID >, where the Session ID is used to indicate the Session identifier corresponding to the Session data, and the Redis ID is used to indicate the device identifier corresponding to the first cache device.

step 2051, the first application server obtains the proxy server list.
Step 2052, the first application server selects the first proxy server from the proxy server list, and sends a cache command to the first proxy server, where the cache command includes the session identifier and the cache identifier, so that the first proxy server queries the cache device corresponding to the cache identifier, and obtains session data corresponding to the session identifier from the corresponding cache device.
In the embodiment of the invention, the proxy server list is established, so that when the cache equipment fails, the proxy server in the proxy server list can send the cache command to other cache equipment, thereby acquiring the session data to provide service for the Web server.
In the embodiment of the present invention, further, the method further includes: and calculating a fragment value corresponding to the session identifier according to the session identifier through a Hash algorithm, and storing the corresponding relation between the fragment value and the cache device in the proxy server list.

The final slice layout is shown in table 2 below:
TABLE 2
| First cache device | Second cache device | Third cache device |
| 0-340 | 681-1023 | 341-680 |
By implementing the fragment layout of table 2 above, the session data corresponding to the 341-680 fragments will be stored in the third cache device, and the session request corresponding to the subsequent fragment will be forwarded to the third cache device. It should be noted that the number of fragments stored in each cache device is the same.
In the embodiment of the present invention, further, the method further includes: and carrying out capacity reduction on a plurality of cache devices.

And step 206, if the first application server is in a halt state, sending a second session request to a second application server, wherein the second session request comprises a cache identifier and a session identifier.
In the embodiment of the invention, when the first application server fails, the Web server distributes the second session request to the second application server, so that the session data is acquired by the second application server, and the normal operation of the service is realized. It should be noted that the second application server may comprise any available node server. The query mode of the second application server can be any available node server queried by the Web server through a load management algorithm.
