Topic: log specific response header for unset header

[vhochstein]

Hi,

I m using Apache 2.4.6 on RedHat Linux, which is in front of a tomcat Application Server via ProxyPass and ProxyPassReverse configuration.

Tomcat is returning a specific header which I would like to log to my accesslog using LogFormat:
LogFormat "%h,USER=%u,%t,METHOD=%m,URI=%U%q,RESPONSE=%>s,SIZE=%B,DURATION=%D,REFERER=%{Referer}i,USERAGENT=%{User-Agent}i,meinHeader=%{X-Specific-Header}ohist" combined

In addition X-Specific-Header must be removed by apache cause information must not be shown in apache response to client. (Header unset X-Specific-Header)

Unfortuently, it seems that unset header process is being done BEFORE access log is written, cause access log always shows an empty value for X-Specific-Header

Any idea how I might be able to log AND to remove Response Header ?

Thanks a lot for your help in advance
