Custom error CODES

Hi there,

following situation:

We use custom error codes like "852" to report special errors in a Java web
application. We use Apache 1.3 together with the Websphere Application
Server 4 from IBM which handles all the requests for dynamic content.

If we create a custom error in the web application prior to a request and
send it back from websphere via apache to the client, Apache seems to not
understand the error code and reports some standard error to the client. If
we use Websphere standalone, websphere reports the custom error code and the
reason phrase correctly to the client.

Do I have to add anything in the httpd.conf? "ErrorDocument 852 /error.html"
does not work! Apache reports that it does not know this custom error Code.

Thanks for any help or advice,

Malte
