|
||
content cache that can be used to cache either local or proxied content.
|
||
<code class="module"><a href="../mod/mod_cache.html">mod_cache</a></code> requires the services of one or more storage
|
||
management modules. Two storage management modules are included in
|

the base Apache distribution:</p>

<dd>implements a memory based storage manager.
|
||
<code class="module"><a href="../mod/mod_mem_cache.html">mod_mem_cache</a></code> can be configured to operate in two
|
||
modes: caching open file descriptors or caching objects in heap storage.
|
||
<code class="module"><a href="../mod/mod_mem_cache.html">mod_mem_cache</a></code> can be used to cache locally generated content

or to cache backend server content for <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code> when

<p>In the event that a document does not provide an expiry date but does
|
||
provide a last-modified date, an expiry date can be calculated based on
|
||
the time since the document was last modified. The
|
||
<code class="directive">CacheLastModifiedFactor</code> directive specifies a
|
||
<var>factor</var> to be used in the generation of this expiry date
|
||
according to the following formula:
|
||
|
||
<code>expiry-period = time-since-last-modified-date * <var>factor</var>
|
||
expiry-date = current-date + expiry-period</code>
|
||
|
||
For example, if the document was last modified 10 hours ago, and
|
||
<var>factor</var> is 0.1 then the expiry-period will be set to
|
||
10*0.1 = 1 hour. If the current time was 3:00pm then the computed
|
||
expiry-date would be 3:00pm + 1hour = 4:00pm.
|

|

If the expiry-period would be longer than that set by
|
||
<code class="directive">CacheMaxExpire</code>, then the latter takes
|
||
precedence.</p>
|
||
|

<div class="example"><p><code>
|

CacheLastModifiedFactor 0.5

|

<p>The <code class="directive">CacheMaxExpire</code> directive specifies the maximum number of
|
||
seconds for which cachable HTTP documents will be retained without checking the origin
|
||
server. Thus, documents will be out of date at most this number of seconds. This maximum
|
||
value is enforced even if an expiry date was supplied with the document.</p>
