Filter X Protocol design question


    I have a special situation where the message is been wrapped
    by more  then one protocol.
    Ex. <proto1 header> <proto 2 header> <msg> <proto2 trailer > <proto1 
trailer>

    Where is the best place to implement the protocol treatment , in a 
protocol(encoder,decoder) or
    in a Fielter?
   

    Thanks in advance

Joao,

Since the protocol stuff is a filter, it will be in a filter  
regardless. Sounds like you could stand to use two "protocol  
filters". You could use MINA's for the proto1 handling, and then  
perhaps your own for proto2?

Alternately, you could patch MINA's filter to allow it to be added  
twice, (and then contribute the patch back! :)
