Class GetStaticResourceAction

java.lang.Object

com.technia.tvc.struts.action.Action

com.technia.tvc.core.actions.TVCAction

com.technia.tvc.core.actions.GetStaticResourceAction

public class GetStaticResourceAction
extends TVCAction

This action class can be used to refer to static resources without the need of bothering about the state of the client browser cache.

What we do here is to append the tvc version to the URL. Example:

Calling the method getURL(HttpServletRequest, String) with value of the last argument as "/tvc/core/tvcCommonScript.js" would return an URL like below:

http://server:port/enovia/ tvc-action/static-resource/ 2010.3.0 /tvc/core/scripts/tvcCommonScript.js

When calling this action, we will resolve the path above to the JavaScript /tvc/core/scripts/tvcCommonScript.js

Following response headers are set:

Expires

A value far away in the future

Content-Type

The content type as returned by ServletContext.getMimeType(String)

Cache-Control

Set to "public"

Since:

2010.3.0
