// 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".
//
// 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.
//

// same security rules as those applied to "file" URLs). This means that normal
// pages cannot link to or access URLs of this scheme.
//
// 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.

// http://target.example.com request returns an "Access-Control-Allow-Origin:
