// 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 |target_domain| is non-empty and |allow_target_subdomains| if false only
|
// exact domain matches will be allowed. If |target_domain| contains a top-
|
// level domain component (like "example.com") and |allow_target_subdomains| is
|
// true sub-domain matches will be allowed. If |target_domain| is empty and
|
// |allow_target_subdomains| if true all domains and IP addresses will be
|
// allowed.
|
//
|
// 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.
