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.
