Suppose if I have two jsp pages Page1.jsp and Page2.jsp. And if I call Page2.jsp from Page1.jsp.

How to determine in Page2.jsp that this request has come from Page1.jsp?

I tried using following code in Page2.jsp

request.getRequestURL()

But it gives me URL of Page2.jsp.

You have to use a header with name referer

request.getHeader( "Referer" );

Unlike many other header information, it is not a mandatory header field. Many a times you may not find this header in the request. To overcome that, you need to implement an alternative solution like passing a from request parameter to hold that URI of the page1.

Please refer to an answer on this type of alternate solution here.
