  • Protocol switching for connections to zero-trust proxy
    Patent number: 11811734
    Abstract: An HTTP connection between a client computing device and an application is established through a reverse proxy. A response to the client computing device includes a payload instructing initiation of a non-HTTP connection (e.g., TCP, UDP). The response is modified to replace references to an original port with a dynamic port allocated to the non-HTTP connection and a temporary ACL entry is created. A subsequent connection request addressed to the dynamic port is authorized per the ACL, modified to replace the dynamic port with the original port, and forwarded to the application. Subsequent packets for the non-HTTP connection have port numbers translated between the original and dynamic ports.
