Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Error message DFHWB0723 occurs when an  *
  *                      HTTP web request contains asterisk and  *
  *                      client gets response URL not found.     *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  DFHWBUR LOCATE_URIMAP treats asterisks in a CICS incoming
  HTTP request as invalid. Thus, when a request with asterisks
  arrives, CICS will bypass matching any URIMAP, and return an
  exception. If DFHWBAAX is used as the TCPIPService analyser
  program, then the client will receive a URL not found response.
  If DFHWBADX is used as the TCPIPService analyser program, the
  symptoms seen will vary, and may include msgDFHWB0723. The
  client will receive a '400 Bad Request' response.
  Additional Keywords: WB0723 msgWB0723
  

Problem conclusion

• DFHWBUR has been changed to handle asterisk as normal character
  in HTTP request and continues process the request as normal.
