get the URL from an HttpServletRequest 1

[OhioSteve]

My .jsp pages all call the post method of a servlet. Here is the method's signature:

public void doPost(HttpServletRequest req, HttpServletResponse res)

My servlet needs to learn the caller's url. Several online sources suggest this approach:

String url="";
url=req.getRequestURL().toString();

Unfortunately that returns the *servlet's* url. I want the caller's url.

Try to use getRemoteAddr()

sorry, I gave the wrong answer
try this
httpServletRequest.getHeader("Referer")
