This scenario describes locating a Web accelerator inside the firewall so that most client access to a Web site can be served without traversing the expensive firewall. You can use NetCache as an accelerator in any situation in which accessing the Web server (or streaming server) is expensive, not just with firewalls.
In this scenario, a Web site offering charts of historical stock performance would not want to regenerate an updated set of charts for every ticker symbol at the close of every market day. The reason is that generating the graphic is relatively expensive and most of the charts would probably not be referenced before the next market close renders them obsolete. However, a chart that is referenced is likely to be referenced again soon, and it is costly to regenerate the chart for each reference. In this case, you can configure NetCache as a Web accelerator so that the real server needs to generate a given chart only once. Service to the customer is faster, and the use of the chart-rendering server is less expensive.
