Basically, I created a class that extends "HttpServletRequestWrapper" and a filter class to filter all request. I can see the value in the JSP page. But, when I use a tool "ieHTTpHeader" , which reads the requet parameters in the browser, I'm not finding the values there.
What I'm trying to do is, I need to send the loggedin username in the request header so that, another appliaction running in an iframe can use this value for singlesignon.
So it's working except that a tool isn't showing your faked header? Is that a real problem? The tool is probably just showing you the request as it was originally sent before you wrapped it. Wrapping it doesn't change the request, it just fakes the ability to change it in code.
