WebTester

WebTester is a handy site management tool, the primary purpose of which is to check your site for broken links. It will report both on missing files and on those which exist but aren't referenced. It can also check the validity of your external links. (That way, if someone moves or removes a page to which you've linked, you'll know that the link needs to be updated!) The script is fairly robust; in addition to following "straight" links, it will also parse and follow links in image maps, in text embedded via SSIs, and in CGI-generated pages. It will let you know the effective "download" file size of your pages, and will provide estimates of how long they'll take to download at various connection speeds. Finally, it can create for you a simple "site map" showing, in outline format, all of your site's pages. (The site map can be included via SSIs on other pages.)
