Complete Host header information with -v

Virtual host configurations and portal applications require correct IP address information for proper socket connections, and complete server name information for accurate routing. These special back-end application services require complete server name and port designation information in any requests from browsers. The Host header of a request contains this information and makes it available to the application. When using WebSEAL junctions, this information is supplied to the Host header through the use of the -v junction option. Insufficient or missing server name and port information degrades the performance of virtual hosting and portal applications. In addition, domain cookies set by these applications might not contain sufficient information. Best pratice is to always use both the fully qualified domain name of the junctioned server and the connection port number in the -v option when creating or adding the junction.

For example:

The port designation should be supplied only if we are using a non-standard port number.
