Regarding GET request Status Code:499, how is this number displayed?

Asked 2 years ago, Updated 2 years ago, 91 views

The page you are creating is "Status Code:499"
·Error Occurred
"·Click on the anti-virus software link to display ""Reason: URL of phishing site""

"

I'd like to find out why, but can you tell me what it is from the Network headers tab of the Chrome console?
·Where is 499 issued? Anti-virus software?
·When and on what basis does antivirus software make this decision?

"·To ""Request URL"", do you want to send ""Request Headers"" with ""Query String Parameters""?"
"·Will the GET request result be returned as ""Response Headers"

"·Only ""Response Headers"" is given ""499"", but when you throw a request, (PC's?) anti-virus software intercepts the communication and gives it status?"

What do you want to do in the end
·I don't want to turn off anti-virus software and not display 499
(If I turn off the anti-virus software...)

- 499 is the web server's decision
- Occurs when web UA disconnects before web server sends a response
- Therefore, there is no way that web UA will receive 499
You can see that

I don't know how the antivirus software is implemented, but
-
for reasons such as matching the blacklist decision, not matching the whitelist decision, or other reasons - Anti-virus software is socket-close right after connection is established. - Therefore, 499 is generated from the web server (server side decision and should not be visible to the web UA)
- The antivirus software is acting as if the web server returned 499 to the web UA.
It seems that

If the page is being created, why don't you temporarily add it to the whitelist of the countermeasure software?
We'll think about what we should do in the end when we get into operation.
