## Class JspAwareRequestContext

- java.lang.Object
- - org.springframework.web.servlet.support.RequestContext
  - - org.springframework.web.servlet.support.JspAwareRequestContext

-     public class JspAwareRequestContext
      extends RequestContext

  JSP-aware (and JSTL-aware) subclass of RequestContext, allowing for population of the context from a `javax.servlet.jsp.PageContext`.

  This context will detect a JSTL locale attribute in page/request/session/application scope, in addition to the fallback locale strategy provided by the base class.
