Currently, I have a servlet act as web service.
When I pass in parameters using POST, it will return me an executable binary file (application/octet-stream). However, beside binary file, I would also like to get additional information (in text format) about this binary file.
Is it possible to achieve this by using only single POST request? But, how is it possible, to switch from application/octet-stream to text/plain within single POST response?
It is not possible to change the MIME type within a single response.
However, i think t is possible to put your additional information into the response header using the
HttpServletResponse.addHeadermethod.
