RE: IoHandler Filter

[Kumaran Arul <AK...@woolworths.com.au>]

Hi



I have a requirement where using filters to gunzip the request and gzip
the response.

I have my gunzip(..) logic in the messageReceived(...) callback on my
compression fileter and where can I put mt my 

gzip(...) logic? I want to zip my content in the buffer prior to sending
the response to the peer. 

I cannot use writeRequest(....) or messageSent(...) callbacks because by
the time these methods are fired the response wouldHave already been
sent to the peer.



Cheers
Arul

You need to implement filterWrite(...) in your IoFilter.

Have you looked at the Stream Compression filter that is bundled with
the mina package?  For using zlib on tcp streams, the compression
filter would be your best bet.  Unless your protocol already takes
care of assembling packets correctly.
