Mechanism
The application that wishes to communicate with a remote host opens an HTTP connection to a mediator server, which acts as a relay of communications to and from the remote host. The application then communicates with the mediator server using HTTP requests, encapsulating the actual communications within those requests. The mediator server is required to be in a network location with sufficiently unrestricted connectivity.
The mediator server unwraps the actual data before forwarding it to the remote host in question. Symmetrically, when it receives data from the remote host, it wraps it in the HTTP protocol before sending it as part of an HTTP response to the application.
In this situation, the application plays the role of a Tunneling Client, while the remote host plays the role of the server being communicated with.
