I would like to ask, in some BIG IQ captures, I found response code 0 and 1, in some articles mentioned that response code 0 can appear in Application Event Logs. This indicates no server response to the request and is expected when the request is blocked, while 1 is a bit difficult to find, some articles that discuss http response code, there is a response code -1, means that something went wrong with connection or response handling. The HttpURLConnection is often buggy with keeping connections alive. Is this the same response code?
Or is there any other information that can explain response code 1? Thank you.
