public class RawResponseWriter extends Object implements BinaryQueryResponseWriter
This writer is a special case that extends and alters the
QueryResponseWriter contract. If SolrQueryResponse contains a
ContentStream added with the key CONTENT
then this writer will output that stream exactly as is (with it's
Content-Type). if no such ContentStream has been added, then a
"base" QueryResponseWriter will be used to write the response
according to the usual contract. The name of the "base" writer can
be specified as an initialization param for this writer, or it
defaults to the "standard" writer.

public String getContentType(SolrQueryRequest request, SolrQueryResponse response)
QueryResponseWriter
QueryResponseWriter's must implement this method to return a valid HTTP Content-Type header for the request, that will logically correspond with the output produced by the write method.

QueryResponseWriter
Information about the request (in particular: formating options) may be
obtained from req
but the dominant source of information
should be rsp
.
There are no mandatory actions that write must perform. An empty write implementation would fulfill all interface obligations.
