originAgentCluster function
Origin-Agent-Cluster is a new HTTP response header that instructs the browser to prevent synchronous scripting access between same-site cross-origin pages.
Browsers may also use Origin-Agent-Cluster as a hint that your origin should get its own, separate resources, such as a dedicated process.
Implementation
Callback originAgentCluster() {
return (Req req, Res res) {
res.set('Origin-Agent-Cluster', '?1');
};
}
