I'd like to propose a pair of new TS APIs below. TSReturnCode TSHttpTxnVerifiedAddrSet(TSHttpTxn txnp, const struct sockaddr *addr); TSReturnCode TSHttpTxnVerifiedAddrGet(TSHttpTxn txnp, const struct sockaddr **addr);
The motivation is to enable plugins to provide client's "real" IP address for ATS core and other plugins. Plugins that use the setter function are expected to read clien's real IP address from somewhere (e.g. Forwarded header field), and also check the validity. If a plugin successfully verifies client's IP address, it may call the setter function for later use. The IP address set by a plugin will be used by ATS remap ACL, and other plugins which call the getter function, if they are configured to do so.
