Merhaba,
functions.php ile ana dizinde ki .htaccess'e kod ekleme şansım var mı ?
Eklemek istediğim kodlar ;

## EXPIRES CACHING ##
<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 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 2 days"
</IfModule>
  
## EXPIRES CACHING ##

Wordpress'in codex sayfasında ;
https://codex.wordpress.org/User:Ame...ess_Indirectly
Şu kodları buldum.

/**
 * Get .htaccess contents before being written to file
 *
 * Uncomment the first two lines and to go Settings > Permalinks to see the output.
 */
function my_htaccess_contents( $rules )
{
    // echo '<pre>'. $rules .'</pre>';
    // exit();
    return $rules . "# My little addition!\n";
}
add_filter('mod_rewrite_rules', 'my_htaccess_contents');

Ancak çalışmadı.
