Apache Access appears 501 method not implemented error resolution _linux

Today's web site is open to find hints that 501 method is not implemented to/index.html not supported. I used the Apache environment, and I'm here to introduce a solution.

Some friends say

Server loading Security_module module caused.
If the server-side solution can
The/etc/conf.d/mod_security.conf in the

Loadfile/usr/libxml2.so.2
loadmodule security_module modules/mod_security2.so
loadmodule unique_id_module Modules/mod_unique_id.so

Comment out, it's OK.

Or you can
. htaccess Add the following content

<ifmodule mod_security.c>
secfilterengine off
secfilterscanpost off
</IfModule>

Turn it off.
