org.apache.http.ProtocolException: Invalid header: HTTP/1.1 200 OK
Hi there,
I'm using httpclient (4.1 and also 4.2) and it throws ProtocolException:
Invalid header: HTTP/1.1 200 OK, and does not allow me to access de
webcontent.
Here is the stacktrace :
Caused by: org.apache.http.ProtocolException: Invalid header: HTTP/1.1 200
OK
at
org.apache.http.impl.io.AbstractMessageParser.parseHeaders(AbstractMessageParser.java:226)

at
org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:906)
And here are the Headers from the GET request:
HTTP/1.1 200 OK
Date: Fri, 09 Jan 1970 00:12:58 GMT
Server: Boa/0.94.14rc18-ipcam
Accept-Ranges: bytes
Connection: close
HTTP/1.1 200 OK
Content-Type: multipart/x-mixed-replace;boundary=IPCAMJPG
The problem must be Bold line because it does not respect HTTP/1.1.
Is there any workaround or any fix?
Thanks in advance,
Best regards,
Rafael Pinto

Posted by Sam Crawford <sa...@gmail.com>.
As an example, take a look at the bottom of
http://code.google.com/p/npr-android-app/source/browse/Npr/src/org/npr/android/news/StreamProxy.java
(specifically IcyLineParser and MyClientConnection).
MyClientConnection shows you how to override createResponseParser.
The unknown part for me is whether or not you can extend
BasicLineParser (like the author did for IcyLineParser) and get away
with just overriding parseHeader. This would require handling the
special case of the duplicate status line by returning null or a dummy
Header value in its place. Both are ugly, but then you're already
dealing with a broken web server, so I suspect such concerns are long
since gone!
I'm not able to test it myself right now, but hopefully the above will
provide you the necessary guidance to give it a try yourself. In the
meantime someone else may have a better suggestion than me.
Thanks,
Sam

Hi Sam, thank you very much for your quick response.
Is there any example/tutorial for how should hi implement
createResponseParser?
Thanks in advance,

Re: org.apache.http.ProtocolException: Invalid header: HTTP/1.1 200 OK
Posted by Sam Crawford <sa...@gmail.com>.
The issue will be caused by the web server replying with two "HTTP/1.1
200 OK" headers. The web server you're connecting to is faulty.
As a workaround, I would suggest subclassing
DefaultHttpClientConnection and overriding createResponseParser. See
here for more details:
http://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/impl/AbstractHttpClientConnection.html#createResponseParser(org.apache.http.io.SessionInputBuffer,
org.apache.http.HttpResponseFactory,
org.apache.http.params.HttpParams)
Hope this helps,
Sam
