From the user perspective the user has to repeatedly specify the string '$INCOMING_URL_PATH' in the address endpoints instead of 'services/MyService'. And besides we currently have a very clean design for endpoints.They simply represent EPRs to which messages can be sent to - and that's all they do. IMO message processing logic such as URL rewriting should be done separately. May be what we are looking for is a URL rewrite mediator which can deal with regular expressions and URL rewrite rules. Such a mediator should provide access to the segments of the original URL through expressions such as ${host}, ${port}, ${path} etc. Then one can do a simple URL rewrite as follows: <URLRewrite expression="${protocol}://some.host:8080/${path}"/> <send/> Now this is a more generic thing that we can use anywhere in the Synapse configuration (sequences, proxies etc).
