Description: Identifies the location from where this application is loaded.

For built-in applications, the value will always be an empty string.

If the location is not specified or not known, value is an empty string.

Note that a particular agent may support only certain types of URLs (e.g., only tftp://...). Thus, the valid values of this object are implementation dependent. An agent may respond with an error (e.g., 'wrongValue') to a management SET operation which attempts to modify the value of this object to one which is not supported by the managed device.

The value of this object may be changed at any time. However, note that setting this value for an active row will cause the old application to be deleted, and the new application (i.e. the program at the newly-specified URL) to be loaded.
