Estou com uma dúvida com a questão abaixo:
<filter-mappig>
<filter-name>CompressFilter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>FOWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
Which of the following statements are true about this filter?
A) CompressFilter filter would be invoked for all the resources of the web application when the client calls them.
B) CompressFilter filter will not be applied for resources invoked using the RequestDispatcher mechanism.
C) CompressFilter filter will be applied to all resources invoked via the RequestDispatcher.forward() method.
D) CompressFilter filter will be applied to all resources invoked via the RequestDispatcher.error() method.
E) CompressFilter filter will be applied to all resources invoked via the RequestDispatcher.request() method.
As alternativas certas são a letra A e C, mas minha dúvida é porque a alternativas D e E estão erradas?
