   > @shuoshadow How did you send requests? Please give us a minimal 
reproducible case.
   
   frontend:
   ```javascript
   const initSocket = () => {
       const socketURI = 
`${WEBSOCKET_URL_OBJ[props.namespace]}/api/v1/pod/exec/${props.namespace}/${props.podName}`
   
       socketRef.current = new WebSocket(socketURI)
       socketOnClose()
       socketOnOpen()
       socketOnError()
     }
   
     const socketOnClose = () => {
       socketRef.current.onclose = () => {
         socketRef.current.close()
         termRef.current.write('connet is closed!!!')
         console.log('close socket')
       }
     }
   
     const socketOnOpen = () => {
       socketRef.current.onopen = () => {
         initTerm()
       }
     }
   ```
   
   backend:
   
        logger.Debug("in ExecPod")
        if !ctx.IsWebsocket() {
                ctx.JSON(http.StatusUnsupportedMediaType, 
hr.ErrResponse{hr.ErrorData{hr.ErrorCodePodExecError, "===not websocket 
request==="}})
                return
        }

   415 code was return by backend, !ctx.IsWebsocket() 
   ```golang
   func (c *Context) IsWebsocket() bool {
        if strings.Contains(strings.ToLower(c.requestHeader("Connection")), 
"upgrade") &&
                strings.EqualFold(c.requestHeader("Upgrade"), "websocket") {
                return true
        }
        return false
   }
   ```
   
   it works right by nginx-ingress
