* Layer 5 and Service example, front-end server.
|
|
*
|
|
* This front-end server expects pings, and forward them to
|
|
* the real ping server. When the ping server sends a pong back,
|
|
* the front-end server forwards it to the client.
|
|
*
|
|
* Even if the connection to the ping server is broken, our
|
|
* front-end server will keep storing the ping messages and
|
|
* will forward them when the connection is restored.
|
|
*
|
|
* To run this program, ensure there is a file "frontend_service.cfg"
|
|
* containing the location of the naming service (NSHost, NSPort)
|
|
* in the working directory. The naming service must be running.
