    <p>The Shared Object Cache provides a means to share simple data
 | 
						|
    across all a server's workers, regardless of <a href="mpm.html">thread
 | 
						|
    and process models</a>.  It is used where the advantages of sharing
 | 
						|
    data across processes outweigh the performance overhead of
 | 
						|
    inter-process communication.</p>

 | 
						|
    <p>The shared object cache as such is an abstraction.  Four different
 | 
						|
    modules implement it.  To use the cache, one or more of these modules
 | 
						|
    must be present, and configured.</p>
 | 
						|
    <p>The only configuration required is to select which cache provider
 | 
						|
    to use.  This is the responsibility of modules using the cache, and
 | 
						|
    they enable selecton using directives such as
 | 
						|
    <code class="directive"><a href="./mod/authn_socache.html#authncachesocache">AuthnCacheSOCache</a></code>,
 | 
						|
    <code class="directive"><a href="./mod/ssl.html#sslsessioncache">SSLSessionCache</a></code>, and
 | 
						|
    <code class="directive"><a href="./mod/ssl.html#sslstaplingcache">SSLStaplingCache</a></code>.</p>
 | 
						|
    <p>Currently available providers are:</p>
 | 
						|
    <dl>
 | 
						|
    <dt>"dbm" (mod_socache_dbm)</dt>
 | 
						|
    <dd>This makes use of a DBM hash file.
 | 
						|
     The choice of underlying DBM configuration may be configurable
 | 
						|
     if the installed APR version supports multiple DBM implementations.</dd>
 | 
						|
    <dt>"dc" (mod_socache_dc)</dt>
 | 
						|
    <dd>This makes use of the <a href="http://www.distcache.org/">distcache</a>
 | 
						|
    distributed session caching libraries.</dd>
 | 
						|
    <dt>"mc" (mod_socache_memcache)</dt>
 | 
						|
    <dd>This makes use of the <a href="http://memcached.org/">memcached</a>
 | 
						|
    high-performance, distributed memory object caching system.</dd>
 | 
						|
    <dt>"shmcb" (mod_socache_shmcb)</dt>
 | 
						|
    <dd>This makes use of a high-performance cyclic buffer inside a
 | 
						|
     shared memory segment.</dd>
