Re: mod_vhost_alias 404 / ErrorDocument

mod_vhost_alias takes the requested URL and matches a directory on the 

server.  The point of using mod_vhost_alias is so you don't have to 

create vritual host record for each site on your server.

my domain is setup as a wildcard domain, so *.mydomain.com will not 

produce a DNS error.

Graham Clarke did speak thusly:

Hi - I'd like to setup a meaningful error page for a virtual host 

that uses mod_vhost_alias.   If a visitor enters a url that doesn't 

exist on the server they're served a custom error page.

Here's a simple example:

The vhost has:
VirtualDocumentRoot /var/www/html/customer/%1

Requests for http://samplesite.mydomain.com  will serve 

/var/www/html/customer/samplesite/index.html

However, if the user makes a mistake and enters 

"amplesite.mydomain.com" apache throws an error.

My question is how to catch these cases and show a friendly error 

page rather than an ugly apache error?

Thanks,
Graham

I think you might be confused here.

The example you are giving would likely not even get to Apache in the 

first place as it is likely to be a DNS error you are getting as the 

"amplesite.mydomain.com" subdomain probably does not have a DNS entry.

To verify this, see if you get a valid IP address when you query DNS 

using nslookup or dig for the "amplesite.mydomain.com" host.
