On Apache servers you simply put ErrorDocument directives in your root’s .htaccess file: ErrorDocument 401 /get-the-fuck-outta-here.asp ErrorDocument 403 /get-the-fudge-outta-here.asp ErrorDocument 404 /404handler.php ErrorDocument 410 /410-gone-forever.asp ErrorDocument 503 /410-down-for-maintenance.asp # … Options -Indexes Then create neat pages for each HTTP response code which explain the error to the visitor and offer alternatives. Of course you can handle all response codes with one single script: ErrorDocument 401 /error.php?errno=401 ErrorDocument 403 /error.php?errno=403 ErrorDocument 404 /404handler.php ErrorDocument 410 /error.php?errno=410 ErrorDocument 503 /error.php?errno=503 # … Options -Indexes Note that relative URLs in pages or scripts called by ErrorDocument directives don’t work. Don’t use absolute URLs in ErrorDocument directives itself, because this way you get 302 response codes for 404 errors and crap like that. If you cover the 401 response code with a fully qualified URL, your server will explode. (Ok, it will just hang but that’s bad enough.) For more information please read my pamphlet Why error handling is important. [...] […] I refuse to discuss IIS error handling.

There's a nice tool to build .htaccess file directly on web with a simple form: www . htaccesseditor . com /en.shtml [Delinked, the first .htaccess code generation I've tried produces utterly bullshit. If you use the code for www vs. non-www canonicalization from this page you create an exploit enabling negative SEO.] Best regards, Riccardo Giuntoli. Thank you for this good guide.
