Actually I found one that works with the "least" amount of trickery...
Logging via "%{Via}<h"
And modifying the response headers the same way as the request headers.
Still in my interpretation the "header modification" via request_header_access would fall into the "adaption and redirection" phase - maybe an idea for a change to trunk?
Still - I got my workaround...
Thanks,
Martin

I have listed all the options I could think of, but I missed the
"different logformat" options you mentioned. I think they boil down to:
4) Use multiple stdio/daemon loggers to append records to the same file.
This does not require development (assuming current stdio/daemon code
use O_APPEND when opening a log file). If you do not use NFS and manual
page for open(2) implications are correct, then there should be no
conflicts.
5) Use a single tcp logger address to log to the same file (requires
not-yet-accepted trunk patch to work well). Here is a sketch for such a
logger:
nc -k -l 127.0.0.1 1234 > one-and-only.log
HTH,
Alex.
