Abstract

A first computer system determines whether a URL contains a first value corresponding to an encapsulating protocol. If the URL contains a value corresponding to an encapsulating protocol, the first computer system determines whether the URL contains an operation protocol key indicating that the URL contains a second value corresponding to an operation protocol. If the URL contains a second value corresponding to an operation protocol, the first computer system selects the operation protocol as the protocol to be employed by the first computer system in issuing a communication to a second computer system. A second computer system determines whether a URL it receives contains a first value corresponding to an operation protocol. If the URL contains a first value corresponding to an operation protocol, the second computer system provides a resource targeted to a first computer system in accordance with an encapsulating protocol. The encapsulating protocol is identified by a second value in the URL, and the resource is provided from a resource store that is accessed in accordance with the operation protocol.
