In what ways the headers added to a response could be used ?

Normally all the useful headers have a corresponding setter methods already defined in the HttpServletResponse class.
For example to set the content type you have HttpServletResponse.setContentType, for setting cookies you have HttpServletResponse.addCookie.

So normally you will not need to use HttpServletResponse.setXxxHeader() methods.
