HTTP 403 with empty content

[mokha]

When requesting content which is already cached, it doesn't send proper 403 Header. Which results empty content instead of the cached one.

Solved it by adding the code above in _display function in min controller:

if ($cache['statusCode'] == 304) {
header('Not Modified',true,304);
exit();
}

The full code of the function is:

private function display($files) {
# ci based cache
$cache_name = str_replace('/', '', $this->_request); // this is why we needed that request var

    if (!$cache = $this->read_from_cache($cache_name)) {
        $cache = $this->_minify($files);
        $this->write_to_cache($cache_name, $cache);
    }

    if ($cache['statusCode'] == 304) {
        header('Not Modified',true,304);
        exit();
    }

    foreach ($cache['headers'] as $header => $value) {
        // we don't want to display ETag
        if ($header != 'ETag')
            Header($header . ': ' . $value);
    }
    echo $cache['content'];
    exit;
}
