Looks like you are using some release of Jetspeed-1. That project has =
been retired since 2008.

https://portals.apache.org/jetspeed-1/ =
<https://portals.apache.org/jetspeed-1/>


Seems the cache header logic is hard-coded, so you=E2=80=99ll have to =
override JetspeedVelocityPage in TurbineResources.properties with your =
own implementation.

See TurbineResources.properties
services.VelocityService.default.page =3D JetspeedVelocityPage
Then see JetspeedVelocityPage, it calls super.doBuildBeforeAction, which =
contains the hard-coding in JetspeedTemplatePage.java:

switch (httpLifetime)
{
    case -1:
        break;
    case 0:
        data.getResponse().setHeader("Cache-Control", "no-cache");
        data.getResponse().setHeader("Pragma", "no-cache");
        data.getResponse().setDateHeader("Expires", 0);
        data.getResponse().setDateHeader("Last-Modified", =
System.currentTimeMillis());
        break;
    default:
        data.getResponse().setHeader("Cache-Control", "max-age=3D" + =
httpLifetime);
        data.getResponse().setDateHeader("Expires", =
System.currentTimeMillis() + (httpLifetime * 1000));
        data.getResponse().setDateHeader("Last-Modified", =
System.currentTimeMillis());
        break;
}

To override this behavior, simply write your own velocity page handler =
extending JetspeedVelocityPage, and override the doBuildBeforeAction to =
include your required headers, don=E2=80=99t call =
super.doBuildBeforeAction, and then plug your handler into =
TurbineResources.properties

services.VelocityService.default.page =3D MyVelocityPage
