404 error message url

[Wim Rafera]

Hello!

I want to customize my 404 error message.

In order to provide the best options for the user I need to know the url
that caused the error. How can I find that out from the 404 page with
javascript?

Thanks,
Wim

I want to customize my 404 error message.

Hmm, with JS? This seems like something that should be done on the server
side. But I am no JS guru.

What webserver are you using? How are you directing them to custom error
documents? On my setup (Apache 1.3.29, PHP 4.3.4), and with an
"ErrorDocument 404 /404.php" in my .htaccess file, I can see the document
they tried to access by looking in $_SERVER['REDIRECT_URL'] and
$_SERVER['REQUEST_URI'].

Additionally, $_SERVER['REDIRECT_ERROR_NOTES'] has a human readable error
message like "file does not exist:
/home/path/to/webroot/bogus/file/request.php"

You can find out as the page that causes the error will appear as the
referer for the 404 page. It depends on your platform how you manage your
server errors. Under IIS (Windows Server), you can define custom error pages
for most errors through the IIS control panel.

You can find out as the page that causes the error will appear
as the referer for the 404 page.

E.g. in Perl you get it from $ENV{HTTP_REFERER}. I have a little
Perl script that will generate custom 404 or 403 error messages
if your server allows you to use a CGI for an error document.
