I would like to hide the port value when accessing Alkaline and search from http://search.server.com. How can I use the Apache proxy mechanism?

The Apache proxy mechanism (mod-proxy: http://httpd.apache.org/docs/mod/mod_proxy.html ) allows to hide Alkaline behind a virtual server. Thus users can connect to, for example, http://search.server.com/ and perform search operations. This has been implemented on the http://search.vestris.com/ server (you can login to the management console with username: alkaline-manage , password: manage ).
<VirtualHost your-server-ip>
 ProxyRequests On
 ProxyPass / http://search.server.com:9999/
 NoCache *
 ServerName search.server.com
 ErrorLog logs/search.server.com-error_log
 TransferLog logs/search.server.com-transfer_log
</VirtualHost>
