no the only realy thing that i know most browser really look it up again is
"no-store"
thats why we have that disabled by default:
protected void setHeaders(WebResponse response)
{
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache, max-age=0,
must-revalidate"); // no-store
}
