Hello

I have a webpage with a forms that when it submits, runs a servlet. In that servlet I need to know the webpage who calls the servlet. How can I do?

I´m using Java 8.

Thanks

What I have tried:

I try with several methods of HttpServletRequest, as getQueryString, getServletPath, getServletInfo, getContextPath, getRequestURI, getRequestURL, but neither of those returns the webpage. Most of them returns the name of the servlet, but not the webpage´s name that calls it.
