How do I set cache headers in Apache?

You can set cache headers in Apache using the Header directive in your configuration file. Would you like a specific example?

Yes, please provide an example for static files.

Sure! You can add the following lines to your .htaccess file or your Apache configuration:

<IfModule mod_headers.c>
    <FilesMatch "\.(jpg|jpeg|png|gif|css|js)$">
        Header set Cache-Control "max-age=31536000, public"
    </FilesMatch>
</IfModule>

This sets a cache duration of one year for those file types.

What if I want to set different cache durations for different file types?

You can specify different Header directives for each file type. For example:

<IfModule mod_headers.c>
    <FilesMatch "\.css$">
        Header set Cache-Control "max-age=604800, public"
    </FilesMatch>
    <FilesMatch "\.js$">
        Header set Cache-Control "max-age=31536000, public"
    </FilesMatch>
</IfModule>

This sets a week for CSS files and a year for JavaScript files.
