Because the data changes all of the time, I need to instruct all
browsers that surf to my turbine site to not use their cache nor
any other cache that may be sitting in a proxy server between
the browser and the web server. To do this I currently have:
$page.setHttpEquiv("Cache-Control", "no-cache")
$page.setHttpEquiv("Pragma", "no-cache")
in my default page layout. This clearly adds:
<meta content="no-cache" http-equiv="Cache-Control">
<meta content="no-cache" http-equiv="Pragma">
to the HTML output, but I am not sure if it is actually setting
the HTTP headers - the behaviour I am seeing is that it is
not.
How can I set the actual HTTP headers so that the content
expires immediately? Won't all template driven apps need
to expire their content pretty much immediately?
Thanks,
Scott
