YES! I had this on my todo list as well and will gladly review whatever you
come up with. The specific case I was interested in is adding headers
containg timestamp info. to responses. I would like to add a timestamp
header recording when the request was received and another timestamp (either
append to the existing header or on a new header) just at the point when the
response is actually being sent on the wire. An instrumented client could
use this info to help pinpoint end-to-end performance problems. Would also
be cool to enable passing format strings on a header directive (like
mod_log_config).
