[users@httpd] Apache 2.4 memcached module not caching

[Solo Luke]

Hi I did this configuration:

<IfModule cache_module>

      <IfModule cache_socache_module>
            CacheSocache memcache:localhost:11211
            CacheSocacheMaxSize 512000
            CacheSocacheMaxTime 86400

                 <Location /api>
                       CacheEnable memcache /
                  </Location>

          </IfModule>

</IfModule>

Unfortunately the memcache module does not cache the response in memcached
server. What is wrong?

I want that after first request-response the Apache to cache to server
response in memcached and feature requests to be fetched from memcached.

Is this configuration doing what I want?

I checked the memcached keys but no key is inserted.

Kind regards,
Danny
