Caching
Overview
Content (Image / Graphic / Media) File Delivery Service through Multiple Cache Servers
Caching is a technology that reduces traffic volume and increases response time by hosting frequently requested Web content in a nearby server, and responding to repeated content requests directly from the server memory. The caching service is useful for online shopping malls, tour sites or enterprise homepages with a high volume of multimedia files. The caching service distributes graphic content (images, Flash files, etc.), which are the main causes of degradation in the loading speed of web pages, to multiple caching servers, improving loading performance and greatly reducing the customer¡¯s Web server load, which dramatically improves service stability.
