Scriptlet code in tpl file

Abhihere

Actually, I am middle of a high priority issue where the JSP pages deployed from the TeamSite to the front-end server are not shown immediately.

I reached to a conclusion that if I add some page caching scriptlet code in the tpl file (which is generating the JSP page), then I may be able to solve the problem.
The scriptlet code is given below:

<%
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy server
%>

Now I am stuck up with two problems:

1)Where to add this scriptlet code in the tpl file?
2)How to give java code inside a tpl file? Do we have tag to add java code like for perl code?
Please find the tpl file in the attachment. I am using TeamSite 6.5.
Thanks in advance.
