Apache get particular cookie value from response in httpd.conf

I want to log a cookie value from response in Apache. How can I do that. The closest option is

Logformat "%{Set-Cookie}o" 

this logs all cookies in response.

How can I extract a particular cookie value & log it?

Use the C format string to log a cookie, such as this:

Logformat "%{Foobar}C" 

to log the contents of cookie Foobar.

• mod_log_config: Custom Log Formats, Format String

Logformat "%{Foobar}C" 

This works with request only. If there is a new cookie being set in the response, this will NOT pick that up.
