Configuring portal safe-redirect
Portal safe-redirect filters HTTP requests by HTTP request method, browser type (in HTTP User Agent), and destination URL, and redirects only the permitted HTTP requests. This reduces the risk that the portal Web server cannot respond to HTTP requests because of overload.
