Logging http-request redirect

Help!
1

I’m not seeing log entries when a redirect happens. I have the following code:

http-request redirect location %[capture.req.uri,lower,map(/etc/haproxy/additional.map)] code 302

Is there a way to get haproxy to generate log entries when this matches? Logging is working I have:

global
   log 127.0.0.1    local0
defaults
   log     global
   option httplog

Everything else is going nicely into our splunk server.
