I am faced with the task of writing a JSP code that retrieves the getRequestURL() of the parent frame (the URL shown in the address bar) from a child frame. However, when I attempt to do this, I only obtain the URL of the child frame. Is there anyone who can assist me in obtaining the URL of the parent frame from the child frame?
<%
String s = request.getRequestURL().toString();
out.println(s);
if (s.contains("Password")) {
out.println("Password changed Successfully");
}
%>
I am tasked with creating a JSP code that retrieves the getRequestURL() of the main frame.
The URL used to access the page being returned is not necessarily the same as the one requested. It could simply be a link pointing to that page.
You may consider checking the Referer header, although it should be noted that this information is frequently blocked or unreliable.
