     * Registering a scheme as standard, will allow relative and absolute resources to
     * be resolved correctly when served. Otherwise the scheme will behave like the
     * `file` protocol, but without the ability to resolve relative URLs.
     *
     * For example when you load following page with custom protocol without
     * registering it as standard scheme, the image will not be loaded because
     * non-standard schemes can not recognize relative URLs:
     *
     * Registering a scheme as standard will allow access to files through the

     * cookies) are disabled for non standard schemes. So in general if you want to
     * register a custom protocol to replace the `http` protocol, you have to register
     * it as a standard scheme.
     *
     * `protocol.registerSchemesAsPrivileged` can be used to replicate the
     * functionality of the previous `protocol.registerStandardSchemes`,
     * `webFrame.registerURLSchemeAs*` and `protocol.registerServiceWorkerSchemes`

     * * `foopy:80` - Use HTTP proxy `foopy:80` for all URLs.
     * * `foopy:80,bar,direct://` - Use HTTP proxy `foopy:80` for all URLs, failing
     * over to `bar` if `foopy:80` is unavailable, and after that using no proxy.
     * * `socks4://foopy` - Use SOCKS v4 proxy `foopy:1080` for all URLs.
     * * `http=foopy,socks5://bar.com` - Use HTTP proxy `foopy` for http URLs, and fail
     * over to the SOCKS5 proxy `bar.com` if `foopy` is unavailable.
     * * `http=foopy,direct://` - Use HTTP proxy `foopy` for http URLs, and use no
     * proxy if `foopy` is unavailable.
     * * `http=foopy;socks=foopy2` - Use HTTP proxy `foopy` for http URLs, and use
     * `socks4://foopy2` for all other URLs.
     *
     * The `proxyBypassRules` is a comma separated list of rules described below:
     *
     * * `[ URL_SCHEME "://" ] HOSTNAME_PATTERN [ ":" <port> ]`
     *

     * "https://x.*.y.com:99"
     * * `"." HOSTNAME_SUFFIX_PATTERN [ ":" PORT ]`
     *
     * Match a particular domain suffix.
     *
     * Examples: ".google.com", ".com", "http://.google.com"
     * * `[ SCHEME "://" ] IP_LITERAL [ ":" PORT ]`
     *
     * Match URLs which are IP address literals.
     *
     * Examples: "127.0.1", "[0:0::1]", "[::1]", "http://[::1]:99"
     * * `IP_LITERAL "/" PREFIX_LENGTH_IN_BITS`
     *
     * Match any URL that is to an IP literal that falls between the given range. IP
     * range is specified using CIDR notation.
     *
     * Examples: "192.168.1.1/16", "fefe:13::abc/33".
