getMaxAge() public method

First, it checks for a s-maxage directive, then a max-age directive, and then it falls back on an expires header. It returns null when no maximum age can be established.

public getMaxAge ( ) : integer
return	integer	Number of seconds

    public function getMaxAge()
    {
        if ($this->doContainsContainer('s-maxage')) {
            return (int) $this->doGetContainer('s-maxage');
        }
        if ($this->doContainsContainer('max-age')) {
            return (int) $this->doGetContainer('max-age');
        }
        if ($expires = $this->getExpires()) {
            $expires = \DateTime::createFromFormat(DATE_RFC2822, $expires);
            return $expires->format('U') - date('U');
        }
        return null;
    }
