Can I check is a page present w/ jQuery
<p>If I have a URL, can I check if the page is present or not with jQuery? For example if it returns 400 Error, I'll execute one command and if not 400, another command?</p>

<p>Would I use AJAX call for it? Or what's the best way to handle it?</p>

<p>Sorry, did not realise this was important. URL is not on the same domain...</p>
