Answer 1

I've tried to load seal into a iframe and then put it to where it's intended to be. It works for me. With the help of jQuery. Here it is:

Create .js file (I called it hackseal.js)

$(function () {
    if (typeof(vs_hack) !== 'undefined') {
        return;
    }
    vs_hack = true;
    var iframe = document.createElement('iframe');
    var html = '<script src="url_to_verysign" type="text/javascript"></script>';
    iframe.style.display = 'none';
    document.body.appendChild(iframe);
    iframe.contentWindow.document.open();
    iframe.contentWindow.document.write(html);
    iframe.contentWindow.document.close();
    iframe.onload = function () {
        var copy = ['dn', 'lang', 'tpt', 'vrsn_style', 'splash_url', 'seal_url', 'u1', 'u2', 'sopener', 'vrsn_splash', 'ver', 'v_ua', 're', 'v_old_ie', 'v_mact', 'v_mDown', 'v_resized'];
        for (var copy_i in copy) {
            window[copy[copy_i]] = iframe.contentWindow[copy[copy_i]];
        }
        $('script#seal-sign').replaceWith(iframe.contentWindow.document.body.innerHTML);
    }
});

Change the original code from this

<script type="text/javascript" src="url_to_verysign"></script>

to this

<script id="seal-sign" type="text/javascript" src="url_to_hackseal.js"></script>

If you look at the code, they are using document.write.

The way I handle this is the following

document.write = function(s) {
    document.getElementById('seal-wrapper').innerHTML += s;
}

Of course this is a very simple hack which only works when there's a single script which uses document.write and you know where you want it to be written to.

This is killing my business too. Seriously... +2 to +20 seconds per page load. AFYS?

We are switching to hosting the image locally but still linking to the original URL on Norton. Don't do this. Mark this answer down. It's wrong. It's illegal. But it's practical.

UPDATE:

Real solution is to:

• Call 877-438-8776, x2, x1
• Tell them seal is slow and you have > 10,000 visits per day on your site
• They give you media kit to install on your own site
