SiteCelerate deploys as a reverse proxy, sitting in the data center between Web servers and the outbound Internet router. All content flowing from your Web server or server cluster, be it application data or public Web site content, is optimized and sent to users faster. All users—whether they connect using dial-up, broadband, T1, or wireless—receive corporate applications and Internet content faster without sacrificing visual quality.

A Web page is comprised of content called "objects." Objects can be images or sections of text, such as headlines or product descriptions. Some objects on a Web page, such as news photos, change more frequently than other objects, such as company logos. After the Acceleration Engine individually optimizes each object, SiteCelerate caches each one in its optimized form.

As Web objects age, their cache instructions must be kept current. This means continuous manual updates, which is both time-consuming and expensive. SiteCelerate eliminates the need for manual cache instruction updates by applying proprietary, intelligent algorithms that automatically update and optimize the instructions. SiteCelerate constantly and intelligently tunes the cache-ability of dynamic content, improving the performance of browsers and caches and making fewer requests to origin servers. The end result is faster content delivery to the user and reduced server and network load.
