Displaying custom error pages on different VirtualHosts in Apache

  • 772

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>

  2. 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.
