These web pages are used to configure the TradeAgent Client software. There are 3 other ports over which the TradeAgent Client software must communicate. The first of these is the normal http port, port 80. The last port, port 389, is used to validate certificates with the Certificate Authority. At least once a day, the local, i.e. TradeAgent Software Client, and server certificates will be validated to ensure that they have not been revoked.
Most corporations connected to the Internet have some form of firewall in place.
Many of these won't have the 488 and 389 ports open, some may restrict browsing the web at all by closing port 80. If you can connect to this page, you have resolved the fact that DNS is running on your computer and you have a connection to the Internet. Before proceeding with the next two tests, the user must have received their certificate and TradeAgent Client software. Follow the steps in the Registration Instructions to obtain the certificate and software. Once the user has their certificate and software, the next step is to attempt to login.
