Custom Interceptor

Hello,

I'd like to do search'n'replace on outgoing HTTP requests. I am trying to do
this with an Interceptor. I managed to bind my own Interceptor to the
PRE_STREAM phase, but then I am stuck at replacing message content. I've
studied the LoggingOutInterceptor but it's too complicated and I don't get
how it works.

Is there a simpler piece of code which I could take as an example? Are
Interceptors the right tool for the Job?

Using CXF 2.6.6

Thanx for your help,
Gérald
