get/setAttribute and getParameter...

Hi,
What is more time consuming?

JSP1:
<% request.setAttribute("FLAG", new Boolean("true")); %>
<jsp:include page="JSP2.jsp" flush="true"/>

JSP2:
<% boolean FLAG = ((Boolean)
request.getAttribute("FLAG")).booleanValue();
     if (FLAG) {
       ..........
       ...........
     }
%>

OR?:

JSP1:
<jsp:include page="JSP2.jsp?FLAG=true" flush="true"/>

JSP2:
<% String FLAG = request.getParameter("FLAG");
      if (FLAG.equals('true")) {
         ..........
         ..........
      }
%>

OR?:

JSP1:
<jsp:include page="JSP2.jsp?FLAG=true" flush="true"/>

JSP2:
<% boolean FLAG = (new
Boolean(request.getParameter("FLAG"))).booleanValue();
      if (FLAG) {
         ..........
         ..........
      }
%>


AND, which way is it best practiced.

Thankss for any help!

Hi,

I am not sure which is the best way. I usually use the First one for my
job.

HI Zinger:
answer to this question depends on env conditions
setAttribute method stores the attribute in JVM itself for every session,
while set parameter will pass the attribute as a header information to you
new jsp.
So it all depends on memory available, cpu speed, and no of pages you are
going to use this technique.
Cheers
Hemant
