> Fix For: 1.3.0

> 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();
> }
> }
