ErrorDocument with local URL

[Hokey]

I am experiancing a problem with the ErrorDocument directive in my httpd.conf.

If I use an external URL:
ErrorDocument 404

http://www.myserver.com/errors/404.html

The 404 error page is displayed with no problems.

But if I use a local URL:
ErrorDocument 404 /errors/404.html
OR if I use a customized message
ErrorDocument 404 "There was a 404 error

The server does not redirect to the 404 error page or display the customized message and the browser displays the NCSA hard coded messages.

Does anyone have an idea what could be causing this problem?

Thanks

This can happen if the error document is smaller than a certain size. I don't remember exactly, but I think it is either 128 or 256 bytes.
