<VirtualHost x.x.x.x:80>
        ServerName exchange.mycompany.com
        ServerAlias exchange.ext.mycompany.com exchange
        ServerAdmin xxxxx@xxxxxxxxxxxxx
        DocumentRoot /opt/www/exchange
        Redirect / https://exchange.mycompany.com/
        LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" com
        CustomLog /opt/www/logs/exchange/access_log combined env=!dontlog
        ErrorLog /opt/www/logs/exchange/error_log
</VirtualHost>

 

<IfModule mod_ssl.c>
        SSLRandomSeed startup builtin
        SSLRandomSeed connect builtin

 

<VirtualHost x.x.x.x:443>
        # This secures the server from being used as a third party
        # proxy server
        ProxyRequests Off

 

        # Allows the proxying of a SSL connection
        SSLProxyEngine On
        ProxyVia Off

 

        DocumentRoot /opt/www/exchange
        RequestHeader set Front-End-Https "On"

 

        ServerName exchange.mycompany.com
        ServerAlias exchange.ext.mycompany.com exchange

 

        # Set up SSL to work with this host
        SSLEngine On
        SSLCertificateFile /opt/www/exchange/certs/exchange.cer
        SSLCertificateKeyFile /opt/www/exchange/certs/exchange.key

 

        ProxyPass / https://exchange.mycompany.com/
        ProxyPassReverse / https://exchange.mycompany.com/

 

        ProxyPreserveHost On
        # Log file
        LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" com
        CustomLog /opt/www/logs/exchange/access_log combined env=!dontlog
