Force JSP page Refresh to prevent server cache (available for static include forced refresh)

For JSP pages, the same result is always returned in order to prevent the page from being cached by the server.

It is common practice to add a variable parameter after the client's URL, such as adding a current time.

The method I'm using now is to add the following code to the JSP header:

<%
Request.setattribute ("Decorator", "none");
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
%>

This way, if you have more than one link to the page, you don't need to add all of the parameters.
