Getting a return URL

[Robert Darling]

Hi,

My web application is such that various other web application redirect to it. I want to add a back button to the page so that which ever client cam e to this page i can go back to that client. Does the Request Object in JSP give me any information of where the request originated.

Kind Regards

You can use the HTTP referrer header

request.getHeader("Referer")

Another question. I have 2 web application running on different servers . The first web app redirects t the second web app. In the first one i have the following code

		
			HttpServletRequest request = (HttpServletRequest) (FacesContext.getCurrentInstance().getExternalContext().getRequest());
			request.setAttribute("param",request.getRequestURI());
			HttpServletResponse response=(HttpServletResponse) (FacesContext.getCurrentInstance().getExternalContext().getResponse());
			response.sendRedirect(url);

In this second application for the body on load a call a java script function

showHeader('<%=request.getAttribute("param")%>')

The param variable is null. Whats going wrong? I might add that both aps are in JSF and the first piece of code is written in a backing bean.

Kind Regards,

request attributes arent shared across web application, try using the param1 as a query string parameter, and then in second application, use request.getParameter() to get the value of the param1

That was a obvious solution. But i did not not want the user to see these. Is these not way to hide this information in the request object ?

I don't think that there is any other way to send data when redirecting. I am not sure though,

OK. How can i get the complete path of the current page. Like
