Assess the Need for HTTP Proxy

Before you configure global subscription settings, determine whether you will download subscription updates to your internal network through an HTTP proxy server. Many enterprises require outbound Internet connections to be made through an HTTP proxy server. You can specify credentials for the HTTP proxy server as part of subscription configuration. This lets the subscription proxy bypass the HTTP proxy when attempting to check for updates from the CA Subscription server. With the automatic bypass, no one has to be present during the subscription update process.

If you use an HTTP proxy, have the IP address, port number, and credentials available when starting this configuration.
