PM73544: HOST HEADER NOT SET IN REQUEST MESSAGE ORIGINATING FROM WPS SCA HTTP BINDING

APAR status

• Closed as program error.

Error description

• When an HTTP request is sent from WPS SCA HTTP binding the HOST
  header is not set in the request message.  If this request is
  forwarded to a proxy server which does not set the HOST header,
  the request will result in a HTTP 404 error message.
  
  This fix also requires WAS APAR PM69423.
  

Local fix

  When forwarding requests using a reverse proxy server with SCA
  HTTP binding, the HOST header is not set properly.  In return,
  a default HOST header is appended and the URL not constructed
  correctly.
  

Problem conclusion

• Code changes have been made to both WebSphere Application
  Server and WebSphere Process Server to accomodate this change.
  A customer property must be configured to enable this function.
  Users will add a new JVM custom property using the Admin
  Console. Navigate to:
  Click Servers > Server Types > WebSphere application servers >
  server_name, under Server Infrastructure, click Java
  and process management > Process definition > Java virtual
  machine > Custom Properties.
  Add the custom property,
  "com.ibm.websphere.sca.http.pooling.hcm.UseURLHostForHostHeader"
  , with value "true".  Repeat this step for all JVMs in the
  environment if required.
  
  The APAR PM73544 must be installed in conjunection with PM69423.
  
  Code changes have been integrated and will be in the next fix
  pack.
