///
// Add an entry to the cross-origin access whitelist.
//
// The same-origin policy restricts how scripts hosted from different origins
// (scheme + domain + port) can communicate. By default, scripts can only access
// 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
// JavaScript if both domains set document.domain="example.com".
// 
// This method is used to allow access to origins that would otherwise violate
// the same-origin policy. Scripts hosted underneath the fully qualified
// |source_origin| URL (like http://www.example.com) will be allowed access to
// all resources hosted on the specified |target_protocol| and |target_domain|.
// If |allow_target_subdomains| is true access will also be allowed to all
// subdomains of the target domain.
//
// This method cannot be used to bypass the restrictions on local or display
// isolated schemes. See the comments on CefRegisterCustomScheme for more
// information.
//
// This function may be called on any thread. Returns false if |source_origin|
// is invalid or the whitelist cannot be accessed.
