> Hi!
> I have a very _funny_ behaviour where the HttpClient seems to wrongly interpret the body of an HTTP response as headers, the parsing of which eventually leads to a java.net.SocketTimeoutException.
> The underlying cause of this seems to be a a faulty server response, i.e.,
> {noformat}
> HTTP/1.1 000 status code 000{noformat}
> Thank you Apple! /s
>
> I have managed to trace the origin of the problem to the *method HttpRequestExecutor#canResponseHaveBody* where, as expected, 000 is not considered as a valid status code.
> !canResponseHaveABody.png!
> !doReceiveResponse.png!
> So what happens seems to be that the status line and headers get parsed. The 000 is not considered valid and that ends the processing of the response. Then the rest of the response (the body) seems to go through the parsing procedure again in *DefaultHttpResponseParser#parseHead*. The body is of content type application/json. Eventually the following exceptions gets thrown after a while:

> I'm not really familiar if 000 is even a valid return code. When querying the server with some other HTTP tools like Postman, I do get the json response with a status code 000.
> Do you guys think this is something that can be fixed in HttpClient or at least handled by some sort of an error?
