Local fix Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server users of the    *
*                 webserver plugins version prior to 4.0.5     *
*                 with proxy firewalls.                        *
****************************************************************
* PROBLEM DESCRIPTION: Failover was not working correctly in   *
*                      versions prior to 4.0.5 with proxy      *
*                      firewalls.                              *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The plugin would not mark the app server down when the read
of the app server response after the connect fails.  It would
only mark the app server down if the connect failed.
Problem conclusion
The plugin now marks the app server down when the read fails
rather than only marking the app server down when the connect
fails.
