I can't provide you with specific advice about your internal applications. 
There are
two reasons for this message, however:

1) Duplicate headers in HTTP response (please examine with curl -i <URL>, as the
headers displayed by ratproxy already have dupes eliminated).

2) Character set declared in HTTP headers and in HTML payload do not match.

If you believe that the message is reported in error (for example, there is a
duplicate header, but it is harmless or expected), please let me know.
