APAR status

  • Closed as program error.

Error description

  • If DataPower creates a Via header for the backend server
    containing a "=" or "/" character the backend application may
    fail. Based on the Via header specs, "=" and "/" are not valid
    characters.
    

Local fix

  • Use DataPower's <dp:remove-http-request-header name="Via"/>
    function to remove the specific header.
    

Problem summary

  • Affected are customers using a Multi-Protocol Gateway for
    accessing a backend server.
    
    The "Via" header field DataPower sends to the backend may
    contain characters "/" or "=" which are forbidden characters for
    the "Via" header by RFC2616.
    
    The Multip-Protocol Gateway sends a pseudonym in the Via header
    which is a base64 encoded string and therefore may contain "/"
    or "=".
    

Problem conclusion

  • "/" and "=" are replaced by valid pseudonym characters "!"
    and "-" in the "Via" header.
    
    Fix is available in 3.7.3.16, 3.8.0.10, 3.8.1.9 and 3.8.2.1
