w3 total cache 플러그인 설정방법

1. 플러그인 업로드

2. 플러그인 활성화

3. 플러그인 설정

Page Cache 와 Browser Cache 만 사용한다. (개인별 차이)

Browser Cache에서는
Set expires header 체크

Page Cache에서는
Cache SSL (https) requests 체크 (SSL 사용하고 있을시)
4. htacces 파일 설정

아래코드가 환경에 따라 자동으로 htaccess에 들어가기도 한다.
설정이 필요하다고 메세지가 나올때는 htaccess 파일에 추가해준다.

Edit file /home/namas/wwwhtml/wp.interad.com/wp-config.php and add next lines:

/** Enable W3 Total Cache */

define('WP_CACHE', true); // Added by W3 Total Cache

Edit file /home/namas/wwwhtml/wp.interad.com/.htaccess and add the following rules above the WordPress directives:

# BEGIN W3TC Browser Cache
