How to set HTTP headers (for cache-control)?

2019-01-01 04:33发布

How to enable browser caching for my site? Do I just put cache-control:public somewhere up in my header like this?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
   "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
Cache-Control:public;
>

I am using the latest version of PHP developing on the latest version of XAMPP.

OWASP recommends the following,

Whenever possible ensure the cache-control HTTP header is set with no-cache, no-store, must-revalidate, private; and that the pragma HTTP header is set with no-cache.

<IfModule mod_headers.c>
    Header set Cache-Control "private, no-cache, no-store, proxy-revalidate, no-transform"
    Header set Pragma "no-cache"
</IfModule>

As I wrote (in http://www.williamferreira.net/blog/2011/10/04/controle-de-cache-apache/) is best to use the file .htacces. However beware of the time you leave the contents in the cache.

Use:

<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
Header set Cache-Control "max-age=604800, public"
</FilesMatch>

Where: 604800 = 7 days

PS: This can be used to reset any header
