Abstract: A client request message is received at a policy enforcement system from a client-side application intended for a server-side application. The client request message is forwarded to a server-side application. An application response message from the server-side application is intercepted at the policy enforcement system in response to the client request message, resulting in an intercepted application response message. The intercepted application response message is analyzed in view of context information and a network policy. Code to inject into the intercepted application response message is determined based on the analyzing. The code has instructions for eliminating accumulation of stale computing sessions. The code is injected into the intercepted application response message, resulting in a modified message. The modified message is forwarded to the client-side application for automatically executing the instructions on the client-side application.

Abstract: An example method facilitates dynamic runtime execution of computer code that is selectively injected into messages in accordance with predetermined configuration rules for automatic execution at a message destination. The injection of code into messages, such as messages exchanged during an authenticated computing session, by a policy enforcement system, can be used to efficiently effectuate enhance computing environment security and computing resource use. For example, in a specific embodiment, code for detecting a browser-close event and then terminating a computing session can be automatically executed client side via a browser extension or plugin, thereby helping to eliminate the accumulation of stale computing sessions; thereby mitigating associated security risks and computing resource consumption of stale computing sessions. In another example embodiment, injected code encrypts session cookies, such as via a Time based One Time Password (TOTP).
