How to disable browser caching for a specific JSP?It is possible to keep the browser from caching a JSP page response. The following hints added to the response header seem to prevent most modern browsers from pulling pages out of cache when the same URL is "hit": <% response.setHeader( "Pragma", "no-cache" ); response.setHeader( "Cache-Control", "no-cache" ); response.setDateHeader( "Expires", 0 ); %> The same effect can be achieved by using meta tags in the HTML header: <meta http-equiv="Pragma" content="no-cache"> <meta http-equiv="Cache-Control" content="no-cache"> <meta http-equiv="Expires" content="Sat, 01 Dec 2001 00:00:00 GMT"> The Cache-Control header was added in HTTP 1.1, while the other two were also present in HTTP 1.0. |
