Looks very grotesc. I would not want to have <head> tag just after </body>.

What I suggested, is that you have a look at the HTTP headers being sent
(using some http tracking tool). Like when you use PHPs "header()" function.

You could also enforce this behaviour, by probably placing your meta-tag
contents into the "header()" call:

header('Pragma: no-cache');
header('Cache-Control: no-store, no-cache, must-revalidate, post-check=1, pre-check=2'); // Whatever those do ...
header('Expires: -1');

You could put this somewhere at the top of index.php, and if you do not want
to modify the typo3-source you could also put it into typo3conf/extTables.php
an put and

if (TYPO3_MODE=='FE') {

around it.
