The following error message is appearing about 10 times every minute in our apache error_log:

[Thu Feb 05 15:05:32 2009] [debug] mod_headers.c(566): headers: ap_headers_output_filter()

While everything seems to be working fine Drupal wise and Apache wise in terms of serving up the website and CMS, it is filling the logs up. We are running Drupal 5.1, Apache 2, Centos 4 environment.

Can anyone explain what this entry means and/or suggest what needs to be done to prevent it, or suggest paths for further investigation?

Thanks

I am seeing the same messages after I enabled the Boost module. It is disabled, but the messages persist. Trying to track down a solution which doesn't break the site.

Boost creates a new .htaccess file in the Drupal root, which activates mod_headers and a bunch of rewrite rules.

Check for .htaccess.orig

If it is there, move (rename) .htaccess to .htaccess.boost.

Then copy .htaccess.orig to .htaccess

This restores the original .htaccess, and keeps copies. If you ever want to play with .htacess, you now have a copy of the original just in case.

This should really be a part of the Boost uninstall procedure!
