Hi.I Hope this is the right section.
I need to deploy LimeSurvey on a 3-layered architecture with a Web Server for static resources (i.e. static html, images, css, js) , a Web Server for dynamic (i.e. php files) plus the DB Server.
Is this architecture supported by LimeSurvey? Is it by means of configuration or coding? What is the easiest and fastest way to attain it?

Thanks in advance.

DB on another server : no issue, directly supported.

For css/js and image : it was generated as assets.

The PHP server need write access on this directory when assets is generated.

You can update url and directory : www.yiiframework.com/doc/api/1.1/CAssetManager in config.php file (on Yii array, not LS array). But need update and testing. See basePath and baseUrl


You can surely construct a class (an Yii extension) to save assets in a external server , see github.com/andremetzen/yii-s3assetmanage...bbf2258af/README#L26 for sample.
