WebESC is a utility to help you validate the web links. It is very fast. You can verify links existency, and changes in sizes of remote files. You can compare your site stored locally on your disk to your web site, i.e. can verify if all the files are succesfully uploaded or changed by a hacker. If you have links to other sites you can check broken links and version changes.
