HI

Is the current Azure Application Proxy service support websocket flow ( ws:// or wss:// URLS).We have an application that has it's content (HTML, JavaScript, images ...) hosted by weblogic and a standalone service that provides data through websockets. I created an app proxy for that one and https is working ok but the app is making a websocket call internally and those are failing. Any help you can provide.

    Hello @M Kohli

    Applications that use the WebSocket protocol, for example QlikSense and Remote Desktop Web Client (HTML5), are supported. The following are known limitations:

    • Application proxy discards the cookie that is set on the server response while opening the WebSocket connection.
    • There is no SSO applied to the WebSocket request.
    • Features (Eventlogs, PowerShell and Remote Desktop Services) in the Windows Admin Center (WAC) do not work through Azure AD Application Proxy.

    The WebSocket application doesn't have any unique publishing requirements, and can be published the same way as all your other Application Proxy applications.

    Full WebSocket support is under development
