NetCloak Overview
NetCloak lets you create dynamic, conditional
HTML pages. In this overview we have included
relatively simple examples of what you can do with
NetCloak, but remember that NetCloak works with
other features of HTML like images, tables and
frames, too.
NetCloak Gives You More Information
With NetCloak, you have more information about
the user, and you can tell the user more about your
server. You can include time, date, page access
counts, and other information right in the text of
your HTML pages.

- Your address is .

your password is "".

NetCloak Gives You Cool Stuff
Style and form are important, and giving your
server the ability to do "cool tricks" will make
your site more appealing. NetCloak has some special
features just to help you create cool sites,
including the ability to have your pages change
randomly, or based on the referrer, time of day,
day of week, etc.
- Good
Morning! Good
Afternoon! Good

little early to be webbing?

NetCloak Adds Advanced Features To Your Site
You can combine NetCloak commands to accomplish
more complex tasks with NetCloak. Below are two
examples of more advanced features that you can
implement using NetCloak - but the uses for
NetCloak are almost endless!

will count the number of times each different
graphic is clicked on.
NetCloak Makes Your Site Easier To Manage
NetCloak provides several commands that make
your pages simpler and your site easier to manage.
NetCloak commands like <MACRO>,
<INSERT_MODIFIED>,
<INSERT_FILESIZE>, and
<EXEC_CGI> are just a few of the ways
to simplify everything from common HTML snippets to
downloadable files to using and writing CGIs.
NetCloak's MACRO command can automatically
insert a common header and footer on all of your
pages. Updating all of your pages with a new header
is then as simple as changing the macro, instead of
editing every page individually. The MACRO command
can also insert content from a file, making it easy
to include information from an outside source in
any page.
An example of using macros is the information on
getting to the Maxum Web site:
Your users will always know that your pages are
fresh when you use the INSERT_MODIFIED command to
display the date the page was updated. If you have
downloadable files on your site, INSERT_FILESIZE
will automatically insert the size of the file and
update it if the file changes. The footer on each
of these introduction pages is inserted using
NetCloak's MACRO command, and the update date is
inserted using NetCloak's INSERT MODIFIED command.
NetCloak Gives You New Security Options
When you use NetCloak, you gain password
protection not just for whole documents, but any
portion of those documents. And address protection
means that you can protect links to secure
documents before unauthorized users even see them.
NetCloak commands are executed on the server, so
hidden content is never sent to the client. Users
cannot see what NetCloak has secured by viewing the
HTML source of the page or other means.

only to users with a password that starts with
