A Simple Link Checker using Ajax

In this simple script we use Ajax (Asynchronous JavaScript and XML) to allow all the links on your web pages to be automatically checked for validity every time the page is visited! Can be easily retrofitted to legacy HTML pages. The Ajax call is made to a simple PHP script at the server which checks the links on the page and reports any broken ones to the webmaster via email. The page visitor need never know anything has happened! Free, of course.
