> Accept a query parameter like isCompressionRequired. If this query param is present,
compress the response using gzip. This will ensure less bandwidth usage if field apps are
using mobile data.
> Sample Code for response filter :-
> Inside filter method :-
> if (request.getRequestHeaders().getFirst(HttpHeaders.ACCEPT_ENCODING).contains("gzip"))
{
> 	                response.getHttpHeaders().add(HttpHeaders.CONTENT_ENCODING, "gzip");
> 	                response.setContainerResponseWriter(
> 	                        new Adapter(response.getContainerResponseWriter()));
> 	            }
>   private static final class Adapter implements ContainerResponseWriter {
>         private final ContainerResponseWriter crw;
>         private GZIPOutputStream gos;
>         Adapter(ContainerResponseWriter crw) {
>             this.crw = crw;
>         }
>         
>         public OutputStream writeStatusAndHeaders(long contentLength, ContainerResponse
response) throws IOException {
>            gos = new GZIPOutputStream(crw.writeStatusAndHeaders(-1, response));
>            return gos;
>         }
>         public void finish() throws IOException {
>             gos.finish();
>             crw.finish();
>         }
>     }
