Question

I have two websites, A and B. When I open website A, I am redirected to website B automatically.

What is the function with which I can check what was the full path of website A from which was the redirect?

I was trying to start with:

        logger.info(request.getPathInfo());
        logger.info(request.getPathTranslated());
        logger.info(request.getServletPath());
        logger.info(request.getLocalName());
        logger.info(request.getRemoteAddr());
        logger.info(request.getRemoteHost());
        logger.info(request.getRequestURI());
        logger.info(request.getServerName());

but none of them is correct.

For redirecting I use response.sendRedirect inside Controller.

Thanks for help.

You can try using the optional referer header:

request.getHeader("referer");

But it is important to note that this may not always be populated (specifically IE).

A better solution, if you are in control of both of the websites, is to pass the value somehow when you are doing the redirect. For example, as a GET or POST parameter.

Edit:

As suggested above, you can append query strings to your redirect URL. For example, you might try something like this:

String redirectUrl = "http://my.redirect.com/";

redirectUrl += "?referer=";
redirectUrl += URLEncoder.encode(request.getRequestURL().toString(), "UTF-8");

Then you can just pull this out of the request on the other side.

Use this as a starting point. You may need to manually append other query parameters that may not be part of the getRequestURL() output.
