ETP Browser can request the selected server's capabilities via a standard HTTP request based on a well-known URL format. The result of the request will be displayed in the Results tab.

Server Capabilities
By clicking "Server Capabilities", ETP Browser will use the selected connection URL and convert it to a well-known URL by replacing the WebSocket protocol "ws" with "http" and appending ".well-known/etp-server-capabilities" in order to issue a standard HTTP request.
