The engine starts looking for thefile in the template-dir and searched all the way to the current template. All the config-filesfound on the way are applied in the same order. The last config that gets applied is theone in the template itself if given.<br>The configuration of a template is as easy as you can see in the following:<pre class="code"><Template-Xipe> <options> <cache> <time value="100" /> </cache> </options></Template-Xipe></pre>this would simply cache the template's output (the final html file) for 100 seconds.<br><h2>Dependencies</h2>Mostly it is necessary to cache the output depending on some variables, such as some input parametersor depending on the values set by the previous/next logic of some kind of list view, etc.<br>Therefore you can use the additional tag 'depends' inside the 'cache' tag, which takes anykind of varible that is deinfed in the global namespace.<br>For example:<br><pre class="code"><Template-Xipe> <options> <cache> <time value="1" unit="week" /> <depends value="$_SESSION $myVar $anyVar" /> </cache> </options></Template-Xipe></pre><br>BE WARNED: letting a cache-file depend on i.e. $_REQUEST makes it possible torun a DOS-attack, since a new cache file has to be created everytime anyrequest parameter changes, i.e. 'http://your.site.com/index.php?whatever'this might flood your webservers diskspace.<h2>Syntax</h2>The syntax of the caching tag is:<br><pre class="code"><Template-Xipe> <options> <cache> <time value="x" [unit="week|weeks|day|days|hour|hours|minute|minutes|second"]/> [<depends value="$_SESSION $myVar $anyVar" />] </cache> </options></Template-Xipe></pre></body></html>⌨️ 快捷键说明
