subsequent actions to affect the selected member. The instances where this is the case include

1.6 Installing and Removing Components
You can use the Administration utility to add new Internet components or remove previously
installed components, as well as include your own component on the Manage Components
menu.
To add or remove Internet components, follow these steps:
1. From the Administration utility Main menu, choose Install/Remove Components.
2. If the information from a recent Internet Express installation exists in the /tmp directory,
the Subset Selection form is displayed. Otherwise, the Administration utility prompts you
for the mount point and the CD-ROM device name before displaying the Subset Selection
Form.
The Subset Selection form lists each Internet Express subset, identifies those that are
mandatory, and indicates whether each optional subset has already been installed.
3. On the Subset Selection form:
• To install a component, click on Install.
• To remove a component, click on Remove. (You cannot remove a mandatory subset.)
4. Scroll to the bottom of the form and click on Submit.
To include your own component on the Administration Utility Manage Components menu
(Figure 1-3), create a file in the /usr/internet/httpd/admin/htdocs/osis/components
directory, one line per file, that includes fields with the table category name, component title
and description, and URL link. Each field must be separated by a semi-colon to ensure the file
is correctly parsed for display in the Manage Components table. The category name can be the
same as an existing category or a completely new category.
The following example is the menu configuration file for the IMP Webmail component. (The
IMP Webmail component is part of the Mail category in the Manage Components table.)
Mail;IMP Webmail;/mail/manage_imp.php
If the new component requires a URL that includes the hostname and cluster alias, the following
keywords (Table 1-3) will be substituted with the appropriate value when the keywords appear
in the URL that you provide in the menu configuration file:
Table 1-3 Keywords for URL Line
Substituted ValueKeyword
The current protocol (http or https).http
The current Web server (hostname or cluster alias, and port).HTTP_HOST
The hostname of the local host.HOSTNAME
The port number from the current Web server.PORT
Figure 1-3 shows the manage components with the major Internet Express components grouped
by category.
