HTTP_CACHE_CONTROL does not get set

    I used the plugin to set Cache-Control: max-age=0 on product pages of woocommerce. That works perfect!

    The only problem is that the $_SERVER[‘HTTP_CACHE_CONTROL’] does not get set.

    1. If I press reload of browser button it does get set.
    But just using the plugin with the max-age=0 it does not.

    2. Tested the server with just a php file with the following:

    header("Cache-Control: max-age=0"); //HTTP 1.1

    That also results in $_SERVER[‘HTTP_CACHE_CONTROL’] => max-age=0

    Any suggestions what to do?

    Okay, took a different approach to the problem so this question is no longer valid.

    Hi Herbert,

    Despite resolving the issue yourself, I’m providing the following sample code to demonstrate the “official” method of doing this, in case others would like to do something similar.

    function addh_no_cache_products ( $options ) {
    if ( is_product() ) {
        $options['cache_max_age_seconds'] = 0;
    }
    return $options;
}
add_filter( 'addh_options', 'addh_no_cache_products', 10, 1 );
