Web accelerator

[Web Accelerator] is a service for high-speed and reasonably-priced domestic distribution of web contents. When a website experiences heavy traffic, problems occur such as decreased display speed or a server crash. However, installing [Web Accelerator] makes it possible to perform cache distribution. This decentralizes the load caused by sudden increases in access and stabilizes the display of the website, etc.
