Edit Question
Title
Body
This question has been posted on Stack before, but none so specific as to what I'm trying to understand. The simplest way to check if a URL is corrrect to send a http Head request. But how do you use that to specify the URL ? I found this in a previous post : function UrlExists(url) { var http = new XMLHttpRequest(); http.open('HEAD', url, false); http.send(); return http.status!=404; } But it doesn't seem to run in firebug for a few reasons. My apologies ahead of time for being daft.
