double cache-control header response due to redis settings

[lunaraurora 1]

Hello, i tested with a header checker the file asyncjs.php served from my subdomain - and it results in a twice header cache-control response: 

 

cache-control

private, max-age=3600, max-age=864000

I enabled Redis plugin and i found this portion of code inside the file apRedis.delivery.php:

        $result = $redis->setex($filename, $expire + 86400, $redis->serialize($cache_contents));

I believe is responsible for such double response.. i'm not a dev nor expert, could someone please suggest me how to fix it?

Many thanks

Hi @lunaraurora,

You mention a redis plugin - is this a 3rd party plugin?

Hi, thanks for the reply.

This one: http://documentation.adserverplugins.com/redis-caching-plugin/

Sincerely i don't know if that's an official plugin or such site provides 3rd party plugins

no suggestions?

at the moment i just commented out this from file asyncjs.php:

// The browser is allowed to cache this
// if (!empty($conf['delivery']['assetClientCacheExpire'])) {
//     $expire = (int)$conf['delivery']['assetClientCacheExpire'];
//     header("Expire: ".gmdate('D, d M Y H:i:s \G\M\T', MAX_commonGetTimeNow() + $expire));
//     header("Cache-Control: private, max-age={$expire}");
// }

in way to get only the header directives of the redis plugin:

cache-control

max-age=864000

.. not sure if this is the best solution but fix the double header response
