PreviewCache script

Tuesday 05 July 2005 3:29:05 pm

Hello,

I want to further improve the response times of an ezp 3.5.1 website. TemplateCache, TemplateCompile and ViewCaching are all enabled.

I can not use static cache, since the pages include dynamic elements. Does it make sense to run a small script which generates 'PreviewCache' for a list of nodes/content types, for example folders?
If it does, would you need to run such a script before or after the template compile script (eztc.php)?

Thanks for your help,

Hi,

images variations were generated to? This makes sense in large galleries or with big image sizes.

Greetings, ekke

Hi,

I made this script work in ez 3.6 by defining the path to the ezcontentobjecttreenode class like this:
include_once( 'kernel/classes/ezcontentobjecttreenode.php' );

best regards - and thanks to Sebastian!
