Do you mean the "logging server" should only see the http headers, but not the content? Anyway, no, not possible. Do you mind explaining what you need exactly (I didn't get the "stamp a counter on their header" part)? > The alternative is log but I'm wondering of how efficient is the > logging of all package. What package? And yes, haproxy logging is very efficient. > Is the log async? Its non-blocking, yes. Regards, Lukas
