Well my pages are cached by the browser so I want to find a way to fix this up by using some algo so that if I make some changes within my webpage the browser takes the changed version of the same.

I was trying to explore this method of HttpServlet API but really dont know how to use it. If you have any other way please suggest.

Thanx in advance.

<% response.setDateHeader("Expire",0);
     response.setHeader("Pragma","no-chache");
     if(request.getProtocol().equal("HTTP\1.1"))
      response.setHeader("Chache-control","no-chache");
%>

write this in head tag of the page

<META HTTP-EQUIV="Expires" CONTENT="Tue, 01 Jan 1985 00:00:01 GMT">
   <META HTTP-EQUIV="Pragma" CONTENT="no-cache">      
   <META HTTP-EQUIV="cache-control" CONTENT="no-cache, no-store, must-revalidate">

it is cache only.(sorry for my mistake)

If it is in jsp or HTML page(as JIMMY Proposed) it works.But some browsers say IE 5.5 are not supporting both HTML style or ASP Style or JSP/Servlet Style.But actual procedure to remove the cache is this Only.
