Error description
The following problem has been discovered with the WebSphere
Application Server v 4.01 HTTP Transport:  If a client sends the
HTTP header: ' Expect: 100-continue ' the correct and expected
response according to the HTTP 1.1 standard as described in
RFC2616 is to return: ' HTTP/1.1 100 OK '.  Currently the HTTP
Transport does not return this header.
Local fix Problem summary
****************************************************************
* USERS AFFECTED: All users of WebSphere Application Server    *
*                 V4.0.1 for z/OS and OS/390 using the HTTP    *
*                 Transport and clients that use the HTTP      *
*                 header "Expect: 100-continue".               *
****************************************************************
* PROBLEM DESCRIPTION: The HTTP Transport does not properly    *
*                      handle the "Expect: 100-continue"       *
*                      header.                                 *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The HTTP Transport does not handle the "Expect: 100-continue"
header correctly.  When the header is sent in the request, the
client expects the server to respond with a "100 continue"
response before it will send the data and this does not occur.
Problem conclusion
Support has bee added support to correctly reply with a
"100 continue" response message when the "Expect: 100-continue"
request header is present.

APAR PQ62689 is associated with SERVICE LEVEL W401083 of
WebSphere Application Server V4.0.1 for z/OS and OS/390.
