Problem summary
**************************************************************** * USERS AFFECTED: All * **************************************************************** * PROBLEM DESCRIPTION: CICS Web Support with a host name that * * contains an underscore character causes * * the request to fail with a 400 BAD * * REQUEST error message. * **************************************************************** When CICS is processing a URL that contains an underscore, DFHWBSR calls a routine that validates the characters in the URL. This routine reports that _ is invalid.
Problem conclusion
DFHWBSR has been changed to no longer call the code that invalidates the underscore.
