We are playing with eTags for caching, and would like to use an MD5 of the page output as the eTag. So, my question is, how can I get the complete page output into a string, without changing the eventual display?

I tried doing this:

$eTag = md5(
    $this->view->render(
        'controller/view',
        array(
            '',
            '',
            '',
        )
    )
);
$this->response->setHeader('E-Tag', $eTag);

But it screws up my output by putting the views/index.volt twice into the browser.

Found it!

For those who are interested:

$eTag = md5(
    $this->view->getRender('controller', 'view')
);
