Abstract
A remote user sends a user request to a relay server that, in turn, forwards the user request (modified or unmodified) through a reverse session-origination (RSO) tunnel to an on-premises network client. In other words, while the user requests flow from outside the client network to the client network, the requests of the delivery protocol for the tunnel flow in the reverse direction, i.e., from the client network toward the relay server and/or the remote user. A server agent, executing client side, generates delivery-protocol requests so that the server can wrap user requests in delivery-protocol responses. In addition, the server agent unwraps user requests and forwards them to their intended destination in the client network. To minimize any time the server would have to wait for a delivery-protocol request, the server agent can generate dummy requests whenever no delivery-protocol request is pending at the server.
