gzip: encoding and decoding

Hi All,
 
I tried to find the examples which gzips the request or gunzips the
response. But I was only able to find out that I need to register stream
converters on my streams.
 
But is there a tutorial or guide which would help me gzip the request
and gunzip the response? If yes please point me to the location or if
not, then please let me know the best approach to solve the problem.
 
Cheers,
Adam
