You can't change the contents of a SAML AuthnRequest, often they are
signed. Also, the AssertionConsumerServiceURL's and other URL's in SAML
messages are validated to assure they match the metadata associated with
EntityID (issuer). The addresses used inbound and outbound have to be
correctly handled by the proxy configuration without modifying the
content of the message being passed on the transport.
