  +         <strong>JSSE prior to Java 1.4 incorrectly reports socket timeout.</strong>
  +        </p>
  +        <p>
  +         Prior to Java 1.4, in Sun's JSSE implementation, a read operation that has timed
out incorrect
  +         reports end of stream condition instead of throwing
as expected.
  +         HttpClient responds to this exception by assuming that the connection was dropped
and throws a recoverable
  +         HTTP exception: Error in parsing the status line from the response: unable to
find line starting with "HTTP".
  +         It should instead report " Read timed out". If
you see the "unable to find
  +         line..." message when working with an older version of JDK and JSSE, it can be
caused by the timeout
  +         waiting for data and not by a problem with the connection.
  +        </p>
  +        <p>
  +         <strong>Work-around:</strong> One possible solution is to increase
the timeout value as the server is
  +         taking too long to start sending the response. Alternatively you may choose to
upgrade to Java 1.4 or 
  +         above which does not exhibit this problem.
  +        </p>
  +        <p>
  +         The problem has been discovered and reported by Daniel C. Amadei.

  +         <strong>HttpClient does not work with IBM JSSE shipped with IBM Websphere
Application Platform</strong>
  +        </p>
  +        <p>
  +         Several releases of the IBM JSSE exhibit a bug that cause HttpClient to fail while
detecting the size
  +         of the socket send buffer ( method throws
  +         "Socket closed" exception).
  +        </p>
  +        <p>
  +         <strong>Solution:</strong> Make sure that you have all the latest
fix packs applied. HttpClient users
  +         have reported that IBM Websphere Application Server versions 4.0.6,, 5.1
do not exhibit the problem.
