PHP ErrorDocument (19th July 2007)
At some unknown point, the new error handling for this website will be made available and written about. You can test it by choosing bogus URIs like these:
/blog/2007/404.404/404.404/4040440/tutorials/404/404/404/404.404.404/404/
The breadcrumb displays all the levels just in case the directories are correct. I could adjust this so it only displays the directories which are known to be correct but that requires more maintenance.
