is cached locally to increase the response speed and save bandwidth. Server acceleration, the Cache is deployed on the front-end of the server and serves as the front-end server of the Web server. This improves the performance of the Web server and speeds up access. If multiple Cache acceleration servers are distributed across different regions, You need to effectively manage the Cache network to guide users to access the nearest node and perform global load balancing.
