In fact, the value in the session is ok, but it seems that the proxy is
caching a lot, because the url inn the browser is the Action servlet name
instead of JSP page, so the url /Online/TenancySchedule.do is always the
same and the Actionforward to the jsp is transparent. How can I force the
proxy to regenerate the jsp page, here is my code
public class SelectSiteAction extends org.apache.struts.action.Action {
/** Creates new LogonAction */
public SelectSiteAction() {
}
public org.apache.struts.action.ActionForward
perform(org.apache.struts.action.ActionMapping mapping,
org.apache.struts.action.ActionForm form,
javax.servlet.http.HttpServletRequest request ,
javax.servlet.http.HttpServletResponse response) throws java.io.IOException,
javax.servlet.ServletException {
// Extract attributes we will need
Locale locale = getLocale(request);
MessageResources messages = getResources();
// Validate the request parameters specified by the user
HttpSession session = request.getSession();
ActionErrors errors = new ActionErrors();
System.out.println("SelectSiteAction [Start]");
String strCellIDParam = request.getParameter("CellID");
System.out.println("CellID received in URL " + strCellIDParam);
// Report any errors we have discovered back to the original form
// Is there a currently logged on user?
reqReoUser reoUser = (reqReoUser) session.getAttribute("User");
if (reoUser == null) {
if (servlet.getDebug() >= 1)
servlet.log(" User is not logged on in session "
+ session.getId());
return (servlet.findForward("logon"));
}
// Get Datasource configured from struts-config.xml
DataSource dataSource = (DataSource)
servlet.getServletContext().getAttribute(Action.DATA_SOURCE_KEY);
java.sql.Connection conn = null;
try
{
// Get a connection to database from the Generic Pool
conn = dataSource.getConnection();
// Put a session value specifying the Site ID on which every
report will work
if (session.getAttribute("Site") != null)
session.removeAttribute("Site");
session.setAttribute("Site", strCellIDParam);
System.out.println("Site session value");
System.out.println(session.getAttribute("Site"));
// Put a request attribute with record of the Site
if (session.getAttribute("SiteCard") != null)
session.removeAttribute("SiteCard");
session.setAttribute("SiteCard", reqSiteCard.findByCellID(conn,
Integer.parseInt(strCellIDParam)));
DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT,
locale);
session.setAttribute("Today", df.format(new Date()));
}
catch (SQLException sqle)
{
// servlet.log(sqle);
sqle.printStackTrace();
session.setAttribute("SQLError", sqle);
return (mapping.findForward("failure"));
}
finally
{
try
{
conn.close();
}
catch (SQLException sqle)
{
System.out.println(sqle);
}
conn = null;
}
System.out.println("SelectSiteAction [End]");
return (mapping.findForward("ShowCard"));
// Forward control to the specified success URI
}
}

Fr�d�ric,
If the query string is different between the two requests, it is not likely
to be a page caching problem. The query string is part of the URL, so things
that cache pages by URL will see the two requests as two different URLs.
Try using the request scope, rather than the session scope, for passing the
object from your Action to the JSP page. This is preferable unless you need
to keep the value in the session for some other reason. However, if it does
need to be in the session, it doesn't seem like the action is replacing the
value in the session and needs further review (perhaps you could post the
code that puts/gets the value in the session).
