HandlerExceptionResolvers should prevent caching of response [SPR-7334]

[spring-projects-issues]

marc schipperheyn opened SPR-7334 and commented

The WebContentInterceptor allows you to specify the cache seconds for a request. It processes them in the preHandle method.

However, the postHandle method is empty. It should check whether an error was thrown by the controller and prevent caching it there was.

This is actually more of a problem to be solved by HandlerExceptionResolvers: They should prevent caching in any exceptional case, no matter whether a WebContentInterceptor was involved, and no matter whether cache headers have been set before in general.

As of Spring 3.0.4, AbstractHandlerExceptionResolver has a "preventResponseCaching" bean property which may be set to "true" in order to prevent caching for exception views. Since all of Spring's HandlerExceptionResolver impls extend that base class, this should be available for any choice of resolver now.

This will be available in tonight's 3.0.4 snapshot - feel free to give it an early try...
