Did I misunderstand how Cache works?

[wrobelda]

I just found out that if I set "Cache timeout in seconds" to 0, my articles still get cached for — if my observation is correct — 30 minutes. Only if I set it to low non-zero value, like 1 second, each consecutive RSS requests result in queuing the upstream servers.

This is with OLX bridge, which I wrote myself. Is there something wrong with my implementation, my understanding of cache or is there some bug in RSS-Bridge?

FYI, custom_timeout = true is correctly set in config.ini.php and I do see the Cache timeout in seconds input field in the UI.

I tested custom_timeout and it works. Which cache are you using?

Your bridge is probably producing an exception which has different TTLs.

See:

        if (in_array($response->getCode(), [403, 429, 503])) {
            // Cache these responses for about ~20 mins on average
            $this->cache->set($cacheKey, $response, 60 * 15 + rand(1, 60 * 10));
        }

        if ($response->getCode() === 500) {
            $this->cache->set($cacheKey, $response, 60 * 15);
        }
