This tells Smarty whether or not to cache the output of the templates
|
|
to the <link linkend="variable.cache.dir">
|
|
<parameter>$cache_dir</parameter></link>.
|
|
By default this is set to 0 ie disabled. If your templates generate
|
|
redundant content, it is advisable to turn on
|
|
<parameter>$caching</parameter>, as this will result in significant
|
|
performance gains.

A value of 1 tells Smarty to use the current
|
|
<link linkend="variable.cache.lifetime"><parameter>$cache_lifetime</parameter></link>
|

variable to determine if the cache has expired.

<listitem><para>A value of 2 tells Smarty to use the
|
|
<link linkend="variable.cache.lifetime"><parameter>$cache_lifetime</parameter></link>
|
|
value at the time the cache was generated. This way you can set the
|
|
<link linkend="variable.cache.lifetime"> <parameter>$cache_lifetime</parameter></link>
|
|
just before <link linkend="api.fetch">fetching</link>
|
|
the template to have granular control over when that particular cache expires.
