Issues with logging compressed payloads

[Grupa PZU]

Hello,
I'm having some trouble with the logging feature. What I'm trying to achieve is 
to log the messages that's payload has been compressed (message header includes 
Content-Type: application/fastinfoset). In that scenario the logged payload is 
still in it's binary form, so the logfiles are hardly readable.
Would it be possible to configure the feature so the messages will be decoded 
before logging them?
Regards, Artur
