Configure Apache to act as a reverse proxy for your portal.
To do so, add lines similar to the following example at the
end of httpd.conf:ProxyRequests Off
ProxyPass /portal http://your_portal_server.domain.com:7001/portal
ProxyPassReverse /portal http://your_portal_server.domain.com:7001/portal
This example configuration redirects requests from the Apache Web
server (http://proxy_server.domain.com:80/portal/xyz) to the portal
application server (http://your_portal_server.domain.com:7001/portal/xyz).
You must specify the fully qualified domain name here and for all
other times you type in the server names. For more information on
Apache reverse proxy, see http://httpd.apache.org/docs/mod/mod_proxy.html.
