Displaying custom error pages on different VirtualHosts in Apache

Question

I have a reverse proxy Apache that is moving the request to a Tomcat servlet. The configuration on the Virtual Host in Apache is:

<VirtualHost 10.10.10.10:80> ProxyPass /Site1/ServLet1 http://1.1.1.1/Site1/ServLet1 ProxyPassReverse /Site1/ServLet1 http://1.1.1.1//Site1/ServLet1 ProxyPass /Site2/ServLet2 http://2.2.2.2/Site2/ServLet2 ProxyPassReverse /Site2/ServLet2 http://2.2.2.2/Site1/ServLet1 </VirtualHost> 

Essentially, if it comes to 10.10.10.10 and requests /Site1/ServLet1, route it to /Site1/ServLet1.

if I add

<VirtualHost 10.10.10.10:80> ProxyPass /Site1/ServLet1 http://1.1.1.1/Site1/ServLet1 ProxyPassReverse /Site1/ServLet1 http://1.1.1.1//Site1/ServLet1 ErrorDocument 404 /customerrors/site1/404.html ProxyPass /Site2/ServLet2 http://2.2.2.2/Site2/ServLet2 ProxyPassReverse /Site2/ServLet2 http://2.2.2.2/Site1/ServLet1 </VirtualHost> 

so it will show a custom error for site1 (I set the ErrorDocument), it will be served to both.

How can I have a different 404 error page per site maintaining this kind of configuration?

Thank

Edit:

if I modify the configuration based on the comments below like:

<Location /Site1/ServLet1/> ProxyPass http://1.1.1.1/Site1/ServLet1 ProxyPassReverse http://1.1.1.1/Site1/ServLet1 ErrorDocument 404 /customerrors/site1/404.html </Location> 

Then I can still get to http://1.1.1.1/Site1/ServLet1 but no error page is displayed whatsoever

I'm not sure what you mean by "different VirtualHosts", since these are in the same one.. but I think you'll want to do something like this (and consider moving the ProxyPass statements into the <Location> blocks too, if you can):

<VirtualHost 10.10.10.10:80> ProxyPass /Site1/ServLet1 http://1.1.1.1/Site1/ServLet1 ProxyPassReverse /Site1/ServLet1 http://1.1.1.1/Site1/ServLet1 <Location /Site1> ErrorDocument 404 /customerrors/site1/404.html </Location> ProxyPass /Site2/ServLet2 http://2.2.2.2/Site2/ServLet2 ProxyPassReverse /Site2/ServLet2 http://2.2.2.2/Site2/ServLet2 <Location /Site2> ErrorDocument 404 /customerrors/site2/404.html </Location> </VirtualHost> 

Edit:

To have the Proxy statements reside in the location blocks:

<VirtualHost 10.10.10.10:80> <Location /Site1> ErrorDocument 404 /customerrors/site1/404.html </Location> <Location /Site1/ServLet1> ProxyPass http://1.1.1.1/Site1/ServLet1 ProxyPassReverse http://1.1.1.1/Site1/ServLet1 </Location> <Location /Site2> ErrorDocument 404 /customerrors/site2/404.html </Location> <Location /Site2/ServLet2> ProxyPass http://2.2.2.2/Site2/ServLet2 ProxyPassReverse http://2.2.2.2/Site2/ServLet2 </Location> </VirtualHost>

Make it so that each vhost has it's own VirtualHost definition.

<VirtualHost 10.10.10.10:80> Servername site1.tld ProxyPass /Site1/ServLet1 http://1.1.1.1/Site1/ServLet1 ProxyPassReverse /Site1/ServLet1 http://1.1.1.1//Site1/ServLet1 ErrorDocument 404 /customerrors/site2/404.html </VirtualHost> <VirtualHost 10.10.10.10:80> ServerName site2.tld ProxyPass /Site2/ServLet2 http://2.2.2.2/Site2/ServLet2 ProxyPassReverse /Site2/ServLet2 http://2.2.2.2/Site1/ServLet1 ErrorDocument 404 /customerrors/site2/404.html </VirtualHost> 

You'll also need to ensure that you have a suitable NameVirtualHost definition.
