Use .htaccess to cache image files in the browser.

For image websites, images must be re-downloaded every time the page is opened, which is not only slow, but also a waste of traffic. At this time, you need to use caching to force the browser to cache image files

Cache files, ask how many times the website has been visited, and reduce traffic consumption. 2 caching codes are now provided

Open the .htaccess file and write the following code

Method 1: Unify cache duration

<FilesMatch ".(flv|gif|jpg|jpeg|png|ico|txt|swf|pdf|swf|js)$">
Header set Cache-Control "max-age=2592000"
</FilesMatch>

Method 2: Cache duration according to different file types

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType text/html "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 1 month" #默認文件緩存時長,慎用
</IfModule>

Note:

ExpiresDefault "access 1 month", the default file cache duration, use with caution, otherwise some of your methods will be invalid, such as recording page views, you must refresh the page with F5
