The server has Apache Web server and Netscape iPlanet installed and apparently each Web server's cgi-bin directory is mapped to the same subdirectory. So in order to run a perl CGI script under each Web server, you need to use a (slightly) different URL.

The code is writing session data as files in a certain subdirectory on the server. When using the URL for Apache Web server, you get only 1 session file created for you and this file increases in size (i.e., the report data is appended to your existing session file) when you run a report which allows you to display the details of a specific record listed on the report. But when using the URL for Netscape iPlanet, you get a new session file created when you run the report and again when you try to display the details of a specific record.
