I think the above case is best configured as a gateway service for HTTP:

  user agent <--http--> special  HTTP  gateway  service <--http--> origin
  |                        |               |          |            server
  |---inside portable------| <-asym chan-> |-special--|

So the origin server sees a normal connection from a HTTP client.

The parameters for the special gateway service would presumably be set in a
preferences window of the user agent, in the same way as a proxy can be set
