    *                  mod_deflate                                 *

    ****************************************************************
    z/OS V2R1 added hardware acceleration of the zlib compression
    library used by mod_deflate. To exploit it, applications must
    be rebuilt with a customized compression library.
    

Problem conclusion

  • An alternate "mod_deflate_z.so" was created which uses the z/OS
    customized version of the zlib compression library. In the next
    release, this version will replace mod_deflate.so.
    
    The fix for this issue is targetted for IBM HTTP Server
    fixpack 8.5.5.4.
