I think I got very similar problem. The difference is that I am using ContentExchange which, I believe, will finish processing when '100 continue' is received from server, IIS in my case. But then later real response, 200 OK with content, came back and hence the 'Unexpected data received but no request sent' error message.
Here is a related issue: http://jira.codehaus.org/browse/JETTY-1299?focusedCommentId=275100#comment-275100 and it looks like it just got fixed. _______________________________________________ jetty-users mailing list [email protected] https://dev.eclipse.org/mailman/listinfo/jetty-users
