Abstract:
1. A method for determining an encoding scheme of a uniform resource location (URL) from a plurality of encoding schemes for a clientless secure socket layer virtual private network (SSL VPN) via a proxy, the method comprising: a) receiving, by an intermediary, a response from a server to a client via a first clientless SSL VPN session, the intermediary establishing the first clientless SSL VPN session between the client and the server, the received response comprising a first URL from the server; b) determining, by the intermediary, responsive to a policy, an encoding scheme from a plurality of encoding schemes for modifying the first URL from the server, each of the plurality of encoding schemes providing a different level of security to a clientless SSL VPN session by applying a reversible modification on a given URL to obfuscate at least a portion of the URL, the intermediary maintaining a mapping of each URL modification; and c) modifying, by the intermediary, the URL for transmission to the client in accordance with the determined encoding scheme.
