44 // Add an entry to the cross-origin access whitelist.
45 //
46 // The same-origin policy restricts how scripts hosted from different origins
47 // (scheme + domain + port) can communicate. By default, scripts can only access
48 // resources with the same origin. Scripts hosted on the HTTP and HTTPS schemes
49 // (but no other schemes) can use the "Access-Control-Allow-Origin" header to
50 // allow cross-origin requests. For example, https://source.example.com can make
51 // XMLHttpRequest requests on http://target.example.com if the
52 // http://target.example.com request returns an "Access-Control-Allow-Origin:
53 // https://source.example.com" response header.
54 //
55 // Scripts in separate frames or iframes and hosted from the same protocol and
56 // domain suffix can execute cross-origin JavaScript if both pages set the
57 // document.domain value to the same domain suffix. For example,
58 // scheme://foo.example.com and scheme://bar.example.com can communicate using
59 // JavaScript if both domains set document.domain="example.com".
60 //
61 // This method is used to allow access to origins that would otherwise violate
62 // the same-origin policy. Scripts hosted underneath the fully qualified
63 // |source_origin| URL (like http://www.example.com) will be allowed access to
64 // all resources hosted on the specified |target_protocol| and |target_domain|.
65 // If |target_domain| is non-empty and |allow_target_subdomains| if false only
66 // exact domain matches will be allowed. If |target_domain| contains a top-
67 // level domain component (like "example.com") and |allow_target_subdomains| is
68 // true sub-domain matches will be allowed. If |target_domain| is empty and
69 // |allow_target_subdomains| if true all domains and IP addresses will be
70 // allowed.
71 //
72 // This method cannot be used to bypass the restrictions on local or display
73 // isolated schemes. See the comments on CefRegisterCustomScheme for more
74 // information.
75 //
76 // This function may be called on any thread. Returns false if |source_origin|
77 // is invalid or the whitelist cannot be accessed.
