Methods, systems, computer program products, and methods of doing business by using dynamic capacity-on-demand techniques for re-routing traffic in a distributed computing network. When demand on an enterprise's resources exceeds some predetermined level, dynamic modifications cause static content (such as images) to be served from resources which are external to the enterprise, such as a caching system which is located close to the enterprise's end users. When demand falls below the predetermined level, the modifications are effectively reversed, such that the external resources are no longer used. The predetermined level may apply to a single monitored device, or to a group of monitored devices. The dynamic capacity-on-demand techniques may also be used for dynamic types of content, such as for dynamically re-routing access to an application program executing on an external resource, and may be used for internal capacity-on-demand as well.
