A Simple Link Checker using Ajax

This little project is a slightly different twist on what we can do with Ajax.



Wouldn't it be great if your links were automatically checked each time anyone visited your page? Because Ajax allows us to make a server call without an associated page load/refresh cycle, we can write a routine to list all the links on a web page and send that list to a server-side script which will check them all, and report any broken ones to the webmaster.



Provided that our script is quite efficient, and the pages to be checked don't contain huge numbers of links, our user should never know anything's happening!
