12.3 Port Forwarding and Mod Proxy

Consider an example where myifolder.organization.com/ifolderapp is an internal ifolder application
server and external users need to access this server using the URL
www.myifolder.organization.com. In this scenario, mod proxy can enable the external users to
access the internal iFolder application server by rewriting the external URL < a href = http://
myifolder.organization.com/ifolderapp> foobar </a> to < a href = http://
www.myifolder.organization.com"> foobar </a>. This enables external users to access the internal
iFolder application server without directly exposing the server.
The following figure illustrates how the port forwarding mechanism can be used in conjunction with
mod proxy to handle requests from external users.

The following sections describe port forwarding and mod proxy.

12.4 Key Benefits

One of the key benefits of port forwarding is that it can also be used within a single machine. Port
forwarding is necessary for a standalone computer if any of the following conditions are true:
The computer is using a shared IP address.
The Windows Internet Connection Sharing option is enabled and a NAT-enabled router is being
used.

12.5 Scalability Parameters

Even though this provides an additional layer of access control and security, it does not affect the
scalability of the application. Depending upon the type of setup you deploy, refer to the scalability
parameters section in the respective chapters. For example, if you deploy a single server setup, see
Section 2.3, "Scalability Parameters," on page 16
