Class AbstractMinifyController

java.lang.Object
  org.riotfamily.cachius.spring.AbstractCacheableController
      org.riotfamily.website.minify.AbstractMinifyController

All Implemented Interfaces:

CacheableController, Compressible, BeanNameAware, Controller, LastModified

Direct Known Subclasses:

MinifyCssController, MinifyScriptController

public abstract class AbstractMinifyController
extends AbstractCacheableController
implements LastModified, Compressible

Controller that concatenates resources and optionally compresses or obfuscates them. The result is cached by Cachius and gzipped when possible.

The controller uses a RequestDispatcher to request the resources and captures them using a CapturingResponseWrapper, which allows us to include dynamic resources, too.

Note: This will not work if an included controller uses request.getRequestURI() to look up a resource. Please use ServletUtils.getRequestUri(HttpServletRequest) instead.

6.5
