Does Web Security Service (WSS) support websockets? If so how does the information show in the WSS access logs?


Web Security Service


Web-sockets are supported in Proxy SG and WSS.

You can find the websocket data on the WSS access log via the s-action field as illustrated in Image 1. Another tell-tale of Web-socket usage is the http 101 return code, as the proxy receives an upgrade request to websocket from the client, and this request is fulfilled with sc-status = 101 switching protocol.

Additional Information

The Proxy SG Administration Guide contains more details on how Websockets are handled by the Secure Gateway. This applies to WSS as well.
