To avoid exposing an additional port, AppServer port 2880, you can configure Apache HTTP Server to act as a reverse proxy. 

1. Enable mod_proxy and mod_proxy_http modules using a2enmod script within Apache configuration. 

a2enmod proxy
a2enmod proxy_http

2. Find and open for editing WebSpellChecker config (2_WebInterface.conf) for Apache. 

• File location on Linux-based environments: /etc/apache2/conf-available/2_WebInterface.conf

/etc/apache2/conf-available# nano 2_WebInterface.conf

3. At the very top or end of the file, add ProxyPass with the path to the application server (AppServer).

ProxyPass "/wscservice/api" "http://localhost:2880"
...

4. Save file and restart Apache.

service apache2 restart

5. In your browser, check version and status of the AppServer to verify if it works properly.
