Set Cross-domain Access
Cross-domain access means that the domain in which the resource initiating the request is located is different from the domain in which the resource pointed to by the request is located. For security reasons, browsers will restrict this non-homologous access. By enabling such feature, the users can clear the cache and access the configuration cross domains, and after the object of origin server (BOS) is updated, all caches corresponding to CDN can be updated automatically and synchronously.
