How to know if a JSP file is beeing included by another one?

Question

I have x.jsp that can either be served as the whole response, or being included in several other jsp files.

So how can I know inside x.jsp if it is being included by another file or not?

Answer 1

You can check the value of the attribute javax.servlet.include.request_uri in your x.jsp page. If set, the jsp page was included.
