A method and system for implementing URL scheme proxies. Embodiments of the invention allow URL schemes that are not natively supported by a computer to be supported via proxy, e.g., using a URL scheme that is native to the computer to forward the non-native transport. More specifically, embodiments of the invention allow a first computer system to support a first URL scheme by encapsulating its transport information into another URL scheme that is natively supported by the first computer. The encapsulated information is then forwarded to a second computer system or server which can provide support for the first URL scheme transport. For instance, if the first computer supports http but does not support ftp, then an ftp transport can be encapsulated inside an http transport and then forwarded to an ftp server which can then extract and process the ftp transport. The ftp response can be handled in an analogous fashion. The invention increases the native URL scheme capabilities of a computer system by proxy. In one embodiment, a system registry is used in order to determine which helper code to use for a particular URL scheme. The selection of helper code and whether native or proxy support is selected are tasks that are transparent to the application. The invention can allow a device with no Internet access to act, transparently, as if it has Internet access.

Techniques for assessing the cost of allocation of execution and affecting the allocation of execution are disclosed. The cost of allocation of execution to or between a first computing device (e.g., a mobile device) and one or more computing resource providers (e.g., one or more Clouds) can be determined during runtime of the executable code. It will be appreciated that a computing system can operate independently of the first computing device and one or more computing resource providers and provide execution allocation cost assessment as a service to the first computing device and/or one or more computing resource providers. Execution allocation cost can be assessed (or determined) based on execution allocation data pertaining to the first computing device and/or one or more computing resource providers. By way of example, power consumption of a mobile device can be used as a factor in determining how to allocate individual components of an application program (e.g., weblets) between a mobile phone and a Cloud. The invention is especially suited for Elastic computing environment and systems. In an Elastic computing environment, scalable and dynamic external computing resources can be used in order to effectively extend the computing capabilities beyond that which can be provided by internal computing resources of a computing system or environment.
