Class BackgroundServletRequestWrapper

java.lang.Object

javax.servlet.ServletRequestWrapper

javax.servlet.http.HttpServletRequestWrapper

io.neba.spring.web.BackgroundServletRequestWrapper

All Implemented Interfaces:

javax.servlet.http.HttpServletRequest, javax.servlet.ServletRequest

public class BackgroundServletRequestWrapper
extends javax.servlet.http.HttpServletRequestWrapper

Wraps background requests to prevent exceptions when clients attempt to obtain an existing session, i.e. when HttpServletRequest.getSession(boolean) is invoked with false. In this case, clients must expect a null return value and should handle this case gracefully.
