Hi Sergey,
> If you put your CXF interceptor at POST_PROTOCOL level then it should
work.
I have tried both PRE_PROTOCOL and POST_PROTOCOL, the handleMessage() of
the out handler does get executed but as per tcpmon, the header is never
included. I tried PROTOCOL, but the handleMessage() was never executed.

You have mentioned this before in other threads, however, I am hesitant
since as per user guide the interfaces are to change in the short term.
(http://cwiki.apache.org/CXF20DOC/jax-rs-jsr-311.html#JAX-RS%28JSR-311%29-Filters).
But I'll give it a shot.
