ht://Check is a link checker derived from
ht://Dig. It can retrieve information through
HTTP/1.1 and store it in a MySQL database so that
after a "crawl", ht://Check can return broken
links, anchors not found, content-types, and HTTP
status codes summaries. ht://Check also performs
accessibility checks in accordance with the
principles of the University of Toronto's Open
Accessibility Checks (OAC) project, allowing users
to discover site-wide barriers like images without
proper alternatives, missing titles, etc. A PHP
interface lets the user query and view the results
directly via the Web.
