Configure Apache for IPv6

To enable Apache to work with IPv6 addresses, download IPv6-enabled Apache from https://httpd.apache.org/download.cgi, unzip it, and follow the instructions in README.v6.txt.
Open <apache-httpd-install>\conf\httpd.conf, and locate the Listen directive. Add the directive to make Apache listen on all inbound IP v6 and v4 addresses on any identified port. Listen 80
Modify the VirtualHost tag in <tomcat-install-folder>\conf\auto\mod_jk.conf to enable it to accept all IP v6 and v4 requests by specifying the following:
```
<VirtualHost *:port no> 
.... 
.... 
</VirtualHost>
```
