iFModule for fail-safe .htaccess ^
At least one of the 2 modules needs to be built into Apache; although they are included in the distribution, they are not turned on by default. To find out if the modules are enabled in your server, find the httpd binary and run httpd -l; this should print a list of the available modules. The modules we're looking for are mod_expires and mod_headers.

If they aren't available, and you have administrative access, you can recompile Apache to include them. This can be done either by uncommenting the appropriate lines in the Configuration file, or using the -enable-module=expires and -enable-module=headers arguments to configure (1.3 or greater).

Caching with mod_expires ^
This module controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. The expiration date can set to be relative to either the time the source file was last modified, or to the time of the client access.

These HTTP headers are an instruction to the client about the document's validity and persistence. If cached, the document may be fetched from the cache rather than from the source until this time has passed. After that, the cache copy is considered "expired" and invalid, and a new copy must be obtained from the source.

hướng dẫn tiếng việt dc ko bạn ơi, tiếng anh ko hiểu chi tiết

 

chỉ là leech về thôi ,biết j mà hướng dẫn

 

Cái này hay nè giảm tải cho server

 

Có ai giải thích hộ mấy câu lệnh trong đó ko??

 

Đại khái là nó sẽ không load những thành phần đã load, mà là dùng cái đã có sẵn trong cache của trình duyệt, và ta có thể chỉ định thời gian để nó refresh lại dữ liệu

Cũng đang tìm hiểu thôi, làm đại thấy Google báo là có nhanh hơn và có giảm tải việc load

Thêm vào .htaccess:

<ifModule mod_headers.c>
<filesMatch "\.(jpe?g|png|gif)$">
Header set Cache-Control "public"
</filesMatch>
<filesMatch "\.(css)$">
Header set Cache-Control "public"
</filesMatch>
</ifModule>

<IfModule mod_expires.c>
ExpiresActive on
ExpiresByType text/css "access plus 1 day"
ExpiresByType text/javascript "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"
ExpiresByType application/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/ico "access plus 1 month"
ExpiresByType image/icon "access plus 1 month"
</IfModule>
