Apache 2.2 http accept filter

[Ian Lord]

Hi,

When I start apache2.2, I get the following error:

[Sat Aug 19 11:26:50 2006] [warn] (2)No such file or directory: 
Failed to enable the 'httpready' Accept Filter
[Sat Aug 19 11:26:50 2006] [warn] (2)No such file or directory: 
Failed to enable the 'httpready' Accept Filter
[Sat Aug 19 11:26:50 2006] [warn] (2)No such file or directory: 
Failed to enable the 'httpready' Accept Filter

Here is my config
In /etc/rc.conf:
apache22_enable="YES"
apache22 ssl_enable="YES"
apache22_http_accept_enable="YES"

In /usr/local/etc/apache22/httpd.conf:
AcceptFilter http httpready
AcceptFilter https dataready

Is there anything I am missing in the kernel or somewhere ?
Also, is it better to run with or without httpready ? I read it was 
better performance wide to use it

Thanks a lot
