[Valid_URL]
[Valid_URL] checks the format of a URL parameter. If the parameter appears to be a valid URL then True is returned.
This tag does not check whether the specified server is available. Use [Include_URL] to perform a live check of a remote server.
The optional -Protocol parameter allows a protocol to be specified such as HTTP, HTTPS, MAILTO, FTP, etc. Only URLs which reference that protocol will be returned as valid.
