Configuration essentials for forward proxy chaining

When configured to act as an explicit or transparent forward proxy, Access Policy Manager (APM®) supports forward proxy chaining, with or without an SWG subscription. These configuration elements are key to forward proxy chaining:

  • One or more pools of proxy servers. All servers in a pool must support the same forward proxy mode: explicit or transparent.

  • A per-request policy that includes a Proxy Select agent, which specifies a pool of proxy servers.

    Note: Only the Proxy Select agent signals that a connection must be made to a next hop. A Pool Assign agent does not.

  • An HTTP Proxy Connect profile configured with its state disabled.

  • The virtual server that processes HTTPS traffic for the forward proxy configuration with the disabled HTTP Proxy Connect profile specified.
