# if you are using the Opmantek applications behind an ssl-terminating apache vhost,

### As this is an older version of of Apache we first need to enable the NamedVirtualHost and associate it to IP and port see https://httpd.apache.org/docs/2.2/vhosts/name-based.html
## In particular https://httpd.apache.org/docs/2.2/mod/core.html#namevirtualhost

NameVirtualHost *:80
 
## We can then specify the VirtualHosts and match to the required with ServerName {name} directive
<VirtualHost *:80>
## This should match the servername of the master.
ServerName masterserver.example.com
    <Location "/omk">
        ProxyPass http://localhost:8042/omk retry=5
        ProxyPassReverse http://localhost:8042/omk
    </Location>
    <Location "/es">
        ProxyPass http://localhost:8042/es retry=5
        ProxyPassReverse http://localhost:8042/es
    </Location>
    <Location "/en">
        ProxyPass http://localhost:8042/en retry=5
        ProxyPassReverse http://localhost:8042/en
    </Location>
    <Location "/pt">
        ProxyPass http://localhost:8042/pt retry=5
        ProxyPassReverse http://localhost:8042/pt
    </Location>

## This section is only used if you are using this server as a Master server which is proxying to slaves.
<VirtualHost *:*>
    ## This server ServerName should match 'host' entry in /usr/local/nmis8/conf/Servers.nmis
    ServerName external-name-poller-1.example.com
    
    ProxyRequests on
    ProxyHTMLDoctype XHTML
    ## This URL should point to the internal name of the poller server so this Master can create it's own connection to the slave
    ProxyPass / http://external-name-poller-1.example.com/ retry=5
    ProxyPassReverse / http://external-name-poller-1.example.com/
