Get the website name in the sevlet

HI, I have a requrement to know the website name from where the request has come from.
I created one link that can be used by any no of websites. If any one click on the link the request is come to my application. I want to know in which website the link has been clicked.
Can any one help me please.

You can view the referrer information but that information is optional. Although most browser do sent it I've disabled it and it won't be send if the link is accessed directly so it won't work always.

If the two web sites are under your control then set any request attributes in them , check them in your code .

If the two web sites were not in your control , access the IP address of this web sites and do your logic

And how would you do that?

Look at the methods provided by the HttpServletRequest object.

http://tomcat.apache.org/tomcat-5.5-doc/servletapi/javax/servlet/http/HttpServletRequest.html

With them you can find the domain, contextPath, IP, etc ...

But that is the ip address of the client. Not of the website on which the client clicked on the link.

Yep, just re-read the OP's question (after a cup of coffee) and realized that he was looking for the info from the referrring site.

Thanks for pointing that out.

use this : -

String refererPage = request.getHeader("referer");

Try to print value of refererPage.It will print the name of website from which it is coming.

The referer header was already discussed earlier in this thread.
