If the Warning header is present on an HTTP message, it normally contains information that is intended to be read by a user. If CICS® Web support receives a message with a Warning header, the text associated with the header is written to the CWBW transient data queue.
The messages are written to the CICS-supplied transient data queue CWBW, which is indirected to CSSL. There is a sample definition for the queue in group DFHDCTG.
CWBO is the queue normally used for CICS Web support messages, and CWBW is provided to keep warning messages separate. If you receive too many warning headers, or warning headers that are no longer useful (such as a warning that is always sent by a server in response to a client request that you make repeatedly), you can remove the CWBW transient data queue to suppress these records.
