About Content Handlers for FTP Responses
When creating a response, Integration Server uses the content handler registered for the content type in the lib/mime.types file.
The Integration Server_directory /instances/instance_name/lib/mime.types file contains the mappings of file extension to content type. You can edit the mappings with Integration Server Administrator by selecting Settings > Resources > Mime types. For more information about editing the mappings of the lib/mime.types file, see webMethods Service Development Help.
Note:
If a response has already been created by the pub.flow:setResponse2 service, Integration Server does not use a content handler for the response.
