Ordinarily, HURRTRAK ONLINE Internet does not require proxies to interact with the network services of external sources.  However, in some network configurations the connection between HURRTRAK Online and a remote server is blocked by a "firewall."  Firewalls protect information in internal computer networks from external access. In doing so, firewalls might limit HURRTRAK Online's ability to retrieve information with external sources.

To overcome this limitation, HURRTRAK Online can interact with proxy software. A proxy server sits atop a firewall and acts as a conduit, providing a specific connection for each network service protocol. If you are running HURRTRAK Online on an internal network from behind a firewall, you'll need from your system administrator the names and associated port numbers for the server running proxy software as well as any proxy userid's and password for the HTTP network service. Proxy software retains the ability to communicate with external sources, yet is trusted to communicate with the internal network.
