Petar Petrov created HTTPCLIENT-1902:
----------------------------------------
Summary: Handle "HTTP/1.1 000 status code 000" responses
Key: HTTPCLIENT-1902
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1902
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient (classic)
Affects Versions: 4.5.5, 4.5.2
Reporter: Petar Petrov
Attachments: canResponseHaveABody.png, doReceiveResponse.png
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.

!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:
{code:java}

{code}
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?
