Abstract
Requests are identified as being for a cacheable object or a non-cacheable object according to information included in a Uniform Resource Locator (URL) associated with the object. For example, the URL may include a port designation for requests for cacheable objects (e.g., images and the like). Thus, a request may be recognized as being for a cacheable or non-cacheable object according to the port on which the request is made. In some cases, requests for non-cacheable objects may be made on port 80. A router may be thus configured to recognize a request as being for a cacheable object or a non-cacheable object according to a port on which the request is received and redirect it to a cache as appropriate.
