Question: Setting up custom Apache error documents.
Go into the Domain Management area of the Kattare Members Section. In there you can select the domain you wish to edit. Once you have selected the domain you wish to edit, you can plug in custom error document settings for your domain. Don't forget to hit "Save" when you are done!
In our default setup, you can use the following in the /etc/httpd.conf configuration file. If you've customized your apache install at all, you should be aware of the location of your httpd.conf. (Note that you can also put these in .htaccess files on a per-directory basis.) The format is "ErrorDocument <error-code> <URL>". Most, but not all of these require a relative URL.
ErrorDocument 400 /errors/badreq.html ErrorDocument 401 /errors/noauth.html ErrorDocument 403 /errors/forbid.html ErrorDocument 404 /errors/missing.html ErrorDocument 500 /errors/conferr.html
You can also redirect people off of your site using an external URL.
ErrorDocument 403 http://www.kattare.com/
Do not forget to restart apache after changing the config with an 'apachectl restart'.
