 * ### Scheme
 *
 * Sometimes referred to as *protocol*, A URL's scheme describes what mechanism should be used to
 * retrieve the resource. Although URLs have many schemes (`mailto`, `file`, `ftp`), this class only
 * supports `http` and `https`. Use [java.net.URI][URI] for URLs with arbitrary schemes.
 *
 * ### Username and Password
 *

     * ubiquitous protocols. Applications should only call this method to avoid specific
     * compatibility problems, such as web servers that behave incorrectly when HTTP/2 is enabled.
     *
     * The following protocols are currently supported:
     *
     * * [http/1.1][rfc_2616]
     * * [h2][rfc_7540]
     * * [h2 with prior knowledge(cleartext only)][rfc_7540_34]
