There comes times when you need to have a common page that you are going to be using for lots of pages. This could be a page that has country codes or lists of subjects etc. You need to refer people back to the previous page. This could also be a page that people might have got to by mistake and you want to allow them to go back a page without using JavaScript. Here is a very simple example.
<%
referer=request.servervariables(“http_referer”)
%>Click <a href=”<%= referer %>”>here</a> to go to the previous page
I hope that helps.
