// Register a custom scheme. This method should not be called for the built-in

// If |is_standard| is true the scheme will be treated as a standard scheme.
// Standard schemes are subject to URL canonicalization and parsing rules as
// defined in the Common Internet Scheme Syntax RFC 1738 Section 3.1 available
// at http://www.ietf.org/rfc/rfc1738.txt
//
// In particular, the syntax for standard scheme URLs must be of the form:
// <pre>
// [scheme]://[username]:[password]@[host]:[port]/[url-path]
// </pre>
// Standard scheme URLs must have a host component that is a fully qualified
// domain name as defined in Section 3.5 of RFC 1034 [13] and Section 2.1 of RFC
// 1123. These URLs will be canonicalized to "scheme://host/path" in the
// simplest case and "scheme://username:password@host:port/path" in the most
// explicit case. For example, "scheme:host/path" and "scheme:///host/path" will
// both be canonicalized to "scheme://host/path". The origin of a standard
// scheme URL is the combination of scheme, host and port (i.e.,
// "scheme://host:port" in the most explicit case).
//
// For non-standard scheme URLs only the "scheme:" component is parsed and
// canonicalized. The remainder of the URL will be passed to the handler as-is.
// For example, "scheme:///some%20text" will remain the same. Non-standard
// scheme URLs cannot be used as a target for form submission.
//
// If |is_local| is true the scheme will be treated as local (i.e., with the
// same security rules as those applied to "file" URLs). Normal pages cannot
// link to or access local URLs. Also, by default, local URLs can only perform
// XMLHttpRequest calls to the same URL (origin + path) that originated the
// request. To allow XMLHttpRequest calls from a local URL to other URLs with
// the same origin set the CefSettings.file_access_from_file_urls_allowed value
// to true. To allow XMLHttpRequest calls from a local URL to all origins set
// the CefSettings.universal_access_from_file_urls_allowed value to true.
//
// If |is_display_isolated| is true the scheme will be treated as display-
// isolated. This means that pages cannot display these URLs unless they are
// from the same scheme. For example, pages in another origin cannot create
// iframes or hyperlinks to URLs with this scheme.
//

// per unique |scheme_name| value. If |scheme_name| is already registered or if
// an error occurs this method will return false.

// resources with the same origin. Scripts hosted on the HTTP and HTTPS schemes
// (but no other schemes) can use the "Access-Control-Allow-Origin" header to
// allow cross-origin requests. For example, https://source.example.com can make
// XMLHttpRequest requests on http://target.example.com if the
// http://target.example.com request returns an "Access-Control-Allow-Origin:
// https://source.example.com" response header.
//
// Scripts in separate frames or iframes and hosted from the same protocol and
// domain suffix can execute cross-origin JavaScript if both pages set the
// document.domain value to the same domain suffix. For example,
// scheme://foo.example.com and scheme://bar.example.com can communicate using
