A method for secure communications between a client and one of a plurality of servers performed on an intermediary device coupled to the client and said plurality of servers. In one aspect, the method comprises: establishing an open communications session between the intermediary device and the client via an open network; negotiating a secure communications session with the client; establishing an open communications session with said one of said plurality of servers via a secure network; receiving encrypted data from the client via the secure communications session; decrypting encrypted application data; forwarding decrypted application data to the server via the secure network; receiving application data from the server via the secure network; encrypting the application data; and sending encrypted application data to the client. In a further aspect, an apparatus including a network interface communicating with the public network and the secure network at least one processor, programmable dynamic memory addressable by the processor, and a communications channel coupling the processor, memory and the network communications interface is provided. The apparatus further includes a proxy TCP communications engine, a proxy SSL communications engine, a server TCP communications engine; and a packet data encryption and decryption engine.

An active ingredient, such as particles of a pharmaceutical agent, is uniformly distributed within a transdermal vehicle, such as a gel or other viscous material. The method comprises filling said first container with a non-uniform mixture of a transdermal vehicle and said active ingredient, mounting the first container on a support member, and securing a second container to the first container. The first container has a restricted opening at its proximal end and a piston mounted movably within the first container for movement between a first position proximate said first container distal end to a position proximate said first container proximal end. The second container has a restricted opening at its proximal end and a piston mounted movably within the first container for movement from a first position proximate the second container distal end to a position proximate said second container proximal end. The first container restricted opening and said second container restricted openings are in open communication. The first container's piston is moved from its position proximate the distal end to a position proximate the proximal end and thereby forcing said mixture from the first container into said second container. The positions of the first and second container relative to said support member, are reversed and the process is repeated moving the mixture back and forth between the two containers until a uniform mixture is achieved.

A method for enabling secure communication between a client on an open network and a server apparatus on a secure network. The method is generally performed on a intermediary apparatus coupled to the secure network and the open network. The method includes the steps of negotiating a secure communications session with the client apparatus via the open network; negotiating an open communications session with the server via the secure network; receiving encrypted packet application data having a length greater than a packet length via multiple data packets; decrypting the encrypted packet application data in each data packet; forwarding decrypted, unauthenticated application data to the server via the secure network; and authenticating the decrypted packet data on receipt of a final packet of the segment.
