+ <p>The Shared Object Cache provides a means to share simple data

+<h2><a name="providers" id="providers">Shared Object Cache Providers</a></h2>
+
+ <p>The shared object cache as such is an abstraction. Five 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 selection using directives such as
+ <code class="directive"><a href="./mod/mod_cache_socache.html#cachesocache">CacheSocache</a></code>,
+ <code class="directive"><a href="./mod/mod_authn_socache.html#authncachesocache">AuthnCacheSOCache</a></code>,
+ <code class="directive"><a href="./mod/mod_ssl.html#sslsessioncache">SSLSessionCache</a></code>, and
+ <code class="directive"><a href="./mod/mod_ssl.html#sslstaplingcache">SSLStaplingCache</a></code>.</p>
+ <p>Currently available providers are:</p>
+ <dl>
+ <dt>"dbm" (<code class="module"><a href="./mod/mod_socache_dbm.html">mod_socache_dbm</a></code>)</dt>
+ <dd>This makes use of a DBM hash file.
+ The choice of underlying DBM used may be configurable
+ if the installed APR version supports multiple DBM implementations.</dd>
+ <dt>"dc" (<code class="module"><a href="./mod/mod_socache_dc.html">mod_socache_dc</a></code>)</dt>
+ <dd>This makes use of the <a href="http://distcache.sourceforge.net/">distcache</a>
+ distributed session caching libraries.</dd>
+ <dt>"memcache" (<code class="module"><a href="./mod/mod_socache_memcache.html">mod_socache_memcache</a></code>)</dt>
+ <dd>This makes use of the <a href="http://memcached.org/">memcached</a>

+
+ <dl>
+ <dt>const char *create(ap_socache_instance_t **instance, const char *arg,
+ apr_pool_t *tmp, apr_pool_t *p);</dt>
+ <dd>Create a session cache based on the given configuration string.

+
+ <dt>apr_status_t init(ap_socache_instance_t *instance, const char *cname,
+ const struct ap_socache_hints *hints,
+ server_rec *s, apr_pool_t *pool)</dt>
+ <dd>Initialize the cache. The cname must be of maximum length 16
+ characters, and uniquely identifies the consumer of the cache
+ within the server; using the module name is recommended, e.g.
+ "mod_ssl-sess". This string may be used within a filesystem
+ path so use of only alphanumeric [a-z0-9_-] characters is
+ recommended. If hints is non-NULL, it gives a set of hints for
+ the provider. Return APR error code.</dd>

+
+ <p>Le cache d'objets partagés en tant que tel est une abstraction.
+ Il est implémenté par cinq modules différents. Pour pouvoir
+ utiliser le cache, un ou plusieurs de ces modules doivent être
+ présents et configurés.</p>
+ <p>Le seul élément de configuration consiste à définir le
+ fournisseur de cache à utiliser. Ceci est de la responsabilité des
+ modules qui utilisent le cache, et pour cela, ils activent la
+ sélection via des directives telles que <code class="directive"><a href="./mod/mod_cache_socache.html#cachesocache">CacheSocache</a></code>, <code class="directive"><a href="./mod/mod_authn_socache.html#authncachesocache">AuthnCacheSOCache</a></code>, <code class="directive"><a href="./mod/mod_ssl.html#sslsessioncache">SSLSessionCache</a></code>, et <code class="directive"><a href="./mod/mod_ssl.html#sslstaplingcache">SSLStaplingCache</a></code>.</p>
+ <p>Les fournisseurs actuellement disponibles sont :</p>
+ <dl>
+ <dt>"dbm" (<code class="module"><a href="./mod/mod_socache_dbm.html">mod_socache_dbm</a></code>)</dt>
+ <dd>Celui-ci utilise un fichier de hashage DBM. Le choix de la
+ DBM sous-jacente peut être configurable si la version
+ d'APR installée supporte de multiples implémentations de DBM.</dd>
+ <dt>"dc" (<code class="module"><a href="./mod/mod_socache_dc.html">mod_socache_dc</a></code>)</dt>
+ <dd>Celui-ci utilise les bibliothèques de mise en cache de sessions

+ <dt>"memcache" (<code class="module"><a href="./mod/mod_socache_memcache.html">mod_socache_memcache</a></code>)</dt>

+ <dd>Cette fonction permet d'initialiser le cache. L'argument cname
+ doit avoir une longueur maximale de 16 caractères et permet
+ d'identifier de manière unique l'utilisateur du cache au sein du
+ serveur ; il est recommandé d'utiliser le nom du module, par
+ exemple "mod_ssl-sess". Comme cette chaîne peut être utilisée au
+ sein d'un système de fichiers, il est conseillé de n'utiliser que
+ des caractères alphanumériques [a-z0-9_-]. Si l'argument hints
+ n'est pas égal à NULL, il fournit un ensemble d'indications au
+ fournisseur. La valeur retournée est le code d'erreur APR.</dd>
