auth headers & logging

[steven]

Hi,

I'm rewriting authentication headers on the fly and those rewritten
headers are being logged, but I would like to log the details supplied by
the client as opposed to what I've rewritten them as. I thought of writing
a logging module and passing it a note, but it seems a bit long-winded and
I'm worried about the performance overhead. Is there a more efficient way
of doing this?

Thanks,
