Does Azure Application Gateway support WebSocket connections to VMs?

Question

Hello,

Does Azure Application Gateway support WebSocket connections to applications running on VMs in the backend?

I see https://azure.microsoft.com/en-us/updates/?filters=%5B%22Application+Gateway%22%2C%22Launched%22%5D this

But this seems specific to containers?

Thanks,

Hello Sundar Narayanan

Yes, Azure Application Gateway supports WebSocket connections to applications running on virtual machines (VMs) in the backend.

• This support is not limited to containers; it applies to any backend service that can handle WebSocket connections, including those hosted on VMs.
• Ensure proper functionality by configuring the Application Gateway settings correctly, including enabling the WebSocket protocol in the listener settings.
• Additionally, verify that your backend application can handle WebSocket connections and that any necessary firewall rules are in place to allow traffic.
