Access Gateway provides the following two types of advanced options:
Global options: These settings are applied to all reverse proxies, unless the option is overwritten by an advance proxy service level setting. The global advanced options are disabled by default. See Configuring Global Advanced Options.
Proxy service level options: These settings are valid only for the proxy service for which you enable these. See Configuring Advanced Options for a Domain-Based and Path-Based Multi-Homing Proxy Service.
