ARR3.0 doesn't support WebSocket compression RRS feed

    Hi,

    I am trying ARR 3.0 with IIS10 on Windows 10 as a reverse proxy with WebSocket support, and I could make it work by setting “Sec-WebSocket-Extensions” to an empty value in URL Rewrtie rule, but this will lose WebSocket compression capability. How can I make WebSocket compression work in ARR?

    Thanks,

    Xuefeng

    Hi Xuefeng Wang,

    ARR3.0 doesn't support WebSocket compression

    Due a limitation of ARR 3.0, this component does not support compressed WebSocket frames; therefore, IIS is not capable of routing them. To make the WebSocket Proxy rule work, the WebSocket protocol must be enabled on the root node, but compression must not be enabled on the AcuToWeb node; add "ws_compression" : 0, to your gateway configuration file or clear the Use WebSock compression option on the Gateway Service Properties dialog box.

    More information you can refer to this link: https://www.microfocus.com/documentation/extend-acucobol/1011/GUID-81B323FA-6AE6-438A-A1F5-016D7F45A097.html.

    Best regards,

    Sam
