Link checker


The link checker will locate and check all links on a given page. This takes place in two stages; firstly the page is fetched and all anchor tags are parsed form the page, secondly a singe header is fetched for each of these links and the returned HTTP status is displayed.

If the same link appears more than once on a page, after the first status check the subsequent checks of that (same) link may come from the cached result.
