APAR status

• Closed as program error.

Error description

• IHS is configured to send out a .csv file using:
  MVSDS ON
    MVSDSIndexes ON
    ForceType application/vnd.ms-excel
    CharsetOptions TranslateAllMimeTypes
  
  With this, all the data is in Row 1 and the first data of the
  second record in the file is in the same cell of the last data
  of first record.
  
  This is because IHS opens any files with a Content-Type other
  than 'text/*' or 'application/javascript-x' as binary files.
  Opening the files as binary looks to consume any 0xA bytes when
  sending it to the client.  IHS needs to add a way to force
  files to be opened in text mode for this case.

  ****************************************************************
  Newlines are lost from a MVSDS dataset served with mod_mvsds
  when the Content-Type is not text/* or
  application/x-javascript. When the Content-Type is not text/*
  or application/x-javascript, mod_mvsds will open the file as a
  binary file causing newlines to be lost.
  

Problem conclusion

• mod_mvsds can be forced to open files as text even when the
  Content-Type is not text/* or application/x-javascript by
  setting the environment variable 'mvsds-force-fread-text'. The
  environment variable can be set with the SetEnv or SetEnvIf
  directives.
  
  This fix is targeted for IBM HTTP Server fix packs:
   - 7.0.0.43
   - 8.0.0.14
   - 8.5.5.12
