Hi Ronak,
I do not think the gzip filter logs anything out. To test it is actually
on, you may try
to use the curl [1] client, where you can directly set the
accept-encoding header:
curl -HAccept-Encoding:gzip -HAccept:application/json
http://host/resource | gzip -dc
to see the actual zipped content just omit the gzip command, otherwise
you should see the json output.
HTH,
