Converts HTTP and HTTPS URIs to file URIs and otherwise returns the parameter URI.
Converts HTTP and HTTPS URIs to file URIs and otherwise returns the parameter URI. Such a conversion assumes the existence of a local mirror of one or more internet sites, where the host name in the parameter URI is an immediate sub-directory of the local root directory, and where the URI scheme (such as HTTP) and port number, if any, do not occur in the local mirror. The conversion then returns the URI in the local mirror that corresponds to the parameter URI.
