Abstract:
1. A method performed by an intermediate virtual private network (VPN) device providing a secure VPN connection between a client device and a directory server, the method comprising: intercepting, with the intermediate VPN device, a first request issued by the client device, wherein first request includes an original resource identifier that identifies a directory structure that, when received by the directory server, causes the directory server to output the directory structure in a first graphical directory-browsing user interface that is incompatible with the virtual private network connection; and in response to receiving the resource identifier and without forwarding the original resource identifier to the directory server, generating and sending, with the intermediate VPN device, a web page to the client device via the secure VPN connection, wherein the web page contains an altered resource identifier that identifies the same directory structure and the same directory server identified by the original resource identifier and includes instructions to cause the client device to output a second request to the directory server to produce the directory structure in a second, graphical directory-browsing user interface that is compatible with the VPN connection between the client device and the directory server.
