<identifier>socache_redis_module</identifier>

<compatibility>Available in Apache 2.4.39 and later</compatibility>

<summary>

    <p><module>mod_socache_redis</module> is a shared object cache provider

    which provides for creation and access to a cache backed by the

    <a href="https://redis.io/">Redis</a>

    high-performance, distributed memory object caching system.

    </p>

    <p>This shared object cache provider's "create" method requires a

       comma separated list of memcached host/port specifications. If using

       this provider via another modules configuration (such as

       <directive module="mod_ssl">SSLSessionCache</directive>), provide

       the list of servers as the optional "arg" parameter.</p>

    <highlight language="config">

        SSLSessionCache redis:redis.example.com:12345,redis2.example.com:12345

    </highlight>

    <p>Details of other shared object cache providers can be found

    <a href="../socache.html">here</a>.
