[webkit-dev] How to handle error response on the browser when the HTTP request fails

This is normal. The http connection did not fail : you send your
request and received your response correctly. If you had a DNS error,
some network hazard or anything that made your connection to the
server truly fail then it would be called.

If you want to catch an http error code, you should have a look at
FrameLoaderClient::dispatchDidReceiveResponse. You can then query the
Response about its details (httpStatusCode is likely your friend
here).
