FreeBSD Apache HTTP Accept Filter Error

When Apache web server is starting up in FreeBSD system, Apache loads succcessfully and web server functioning properly, but the following warning error occurs:

[warn] (2)No such file or directory:
Failed to enable the ‘httpready’ Accept Filter

The resolution to the above problem is to a accf_http module, which function is to buffer incoming connections until a certain complete HTTP requests arrive, into FreeBSD kernel by using kernel linker:

kldload accf_http

To permanently load enable HTTP Accept Filter FreeBSD kernel module (accf_http), add the following line into /boot/loader.conf:

accf_http_load=”YES”

Note: The default settings is located in /boot/defaults/loader.cnf. To see the related settings about accf, use:

grep accf /boot/defaults/loader.conf

which will returns:

accf_data_load=”NO” # Wait for data accept filter
accf_http_load=”NO” # Wait for full HTTP request accept filter

    Great solution, thank you. However, when I went to copy and paste the line

    accf_http_load=”YES”

    into my config file, it produced a horrible mess all over my editor. The reason is that you have some fancy directional double quotes, no doubt helpfully supplied by your text editor. When putting in snippets of a config file, however, it would appear that the correct thing to do is always use plain old ascii double quotes.

    Thanks
