Description

There are several issues with parsing response from the server side:

The target server failed to respond
org.apache.http.NoHttpResponseException: The target server failed to respond
        at org.apache.http.impl.conn.DefaultHttpResponseParser.parseHead(DefaultHttpResponseParser.java:95)

        at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:906)

This bug is fixed in HTTPCLIENT-1610

So, it would be very useful if upgrade latest camel to use httpclient 4.4 or latest to avoid such bugs.
