httpd2.2 mod_headers, need a directive for manipulate headers of non-success (non-2xx) responses

[Csaba Kecse-Nagy <kecsolecso@xxxxxxxxx>]

Hello,

I would like to construct a directive in my httpd.conf file that is for all non-success responses of my site.
In the following link http://httpd.apache.org/docs/2.2/mod/mod_headers.html#Header there is a sentence which would be perfect if I could set: "You're adding a header to a non-success (non-2xx) response, such 
            as a redirect, in which case only the table corresponding to 
            always is used in the ultimate response."

Please help me constructing a directive section into the configuration file that handles all not successful (non-2xx) responses. I would like to manipulate some header parameters, something like this:

<LocationMatch "/">
      Header non-success unset Cookiename
</LocationMatch>

Thanks in advance.

Csaba
