The algorithm for searching the outbound proxy is simple. The filter first goes through to the list of outbound proxies and tries to match the hostname in the request-URI of the request to the provided Domain. If it does not find a match, it will take the outbound proxy in the general settings (if provided). If it does find a match, it will replace the hostname part of the request-URI with the Replacement and then send it to the Outbound Proxy. Note that like in all routing decisions, the filter fully supports RFC3264; that means transport layer (tcp, tls, udp) and final destination are determined through DNS NAPTR, SRV and A lookups.
