Error description

• When an HTTP request is received in the HTTP Channel Framework

  a proxy server which does not set the Host header, the request
  will result in a HTTP 404 error message.

  ****************************************************************
  When building an outbound request the HTTP Channel will add a
  Host header, if the header is not present, and add it using the
  value from the remote host. This can end up causing issues if
  the remote host is a proxy and the proxy is not resetting the
  Host header on the inbound request.
  

Problem conclusion

• HTTP Channel was modified to use the URL host for the Host
  header while building an outbound request.
  
  APAR PM76226 is currently targeted for inclusion in WebSphere
  Application Server Fix Pack 7.0.0.29.
