Custom ErrorDocument

[Mauri <lain80@xxxxxxxxx>]

Hi expert,
where I can insert the ErrorDocument directive in my ssl.conf virtualhost ? this is my virtualhost directive

NameVirtualHost myserver:443
<VirtualHost myserver:443>
ServerName myserver
ProxyRequests off   
ProxyPass / https://10.173.100.117:8443/
ProxyHTMLURLMap https://10.173.100.117:8443 /       
<Location />                               
        ProxyPassReverse https://10.173.100.117:8443/
        ProxyHTMLEnable On
        ProxyHTMLURLMap  /      /
        RequestHeader    unset  Accept-Encoding
</Location>
..SSL Directive..
</VirtualHost>

if I insert this directive:

DocumentRoot /var/www/error
        <Directory /var/www/error/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>
ErrorDocument 503 /test.html

this is the entry in my apache log (wrong):
ictservices_ssl_error_log:[Thu Jul 15 20:58:46 2010] [debug] mod_proxy_http.c(56): proxy: HTTP: canonicalising URL //10.173.100.117:8443/prova.html
ictservices_ssl_error_log:[Thu Jul 15 20:58:46 2010] [debug] proxy_util.c(1488): [client 10.173.202.139] proxy: https: found worker https://10.173.100.117:8443/ for https://10.173.100.117:8443/prova.html
ictservices_ssl_error_log:[Thu Jul 15 20:58:46 2010] [debug] mod_proxy_http.c(1960): proxy: HTTP: serving URL https://10.173.100.117:8443/prova.html

I want that if the backend application is down (https://10.173.100.117:8443/) the proxy send to client the local file /var/www/error/test.html

many thanks for any sugget.

Cheers,
Mauri
