Chapter 7
Using Netcaster
Netcaster automatically delivers up-to-date web sites
called channels directly to your desktop. You use Netcaster to:
-
subscribe to just the channels you want and get just the information you
need
-
choose from a ready-made list of interesting web channels in Netcaster's
Channel Finder
-
make any channel into a full-screen webtop. A webtop is an automatically
updated channel that always remains on your screen underneath other windows
that you're working in. With a webtop, you can easily see late-breaking
information on the channel while you're working on other tasks.
-
download any web site and browse it when you're offline (disconnected from
the Internet)
Starting Netscape Netcaster
Start Netscape Netcaster in one of the following
ways:
-
From the Communicator menu, choose Netcaster.
-
(Windows only) Double-click the Netcaster icon on your desktop.
By default, the Netcaster window appears on the right
side of your screen.
About Channel Finder
In the Netscape Netcaster window, Channel Finder
contains a ready-made list of interesting channels. Using Channel Finder,
you can preview channels in the list. When you find channels that you like,
you can add them to your personal list of channels in My Channels. Netcaster
regularly updates Channel Finder, so you should check it often for new
channel listings.
Adding a channel to My Channels
Follow these steps to preview a channel and add it
to My Channels:
-
If Channel Finder isn't already open in the Netcaster window, click the
Channel Finder bar.
-
To preview the channel, click its bar or description.
-
To add the channel to My Channels, click the Add Channel button in the
preview window. After you add the channel to
My Channels, its link appears on a bar in My Channels.
About My Channels
In the Netscape Netcaster window, you use My Channels
to collect links to your favorite channels and web sites.
Follow these steps to view a channel listed
in My Channels:
-
If My Channels isn't already open in the Netcaster window, click the My
Channels bar.
-
Click the channel you want to view. The channel
opens in a Navigator window.
-
To close the channel, choose Close from the File menu in the channel's
Navigator window.
Deleting a channel from My Channels
-
In the Netcaster window, click Options.
-
In the dialog box, select the channel you want to delete.
-
Click Delete.
Setting the default channel
Netcaster is preset to automatically open a channel
each time you start Netcaster. By default, Netcaster opens the Netscape
Channel. You can choose another channel as the default, or specify that
no channel opens when you start Netcaster.
Follow these steps to change your default
channel:
-
In the Netcaster window, click Options.
-
In the dialog box, click the Layout tab.
-
Under Default Channel, select Set Default to, then select the channel you
want to open when Netcaster starts. If you don't want a channel to open
automatically, select None.
-
Click OK.
Making a channel into a webtop
A webtop is a full-screen channel whose content is
anchored to your desktop. The webtop can cover all or part of your screen,
and it remains behind all other application windows until you want to view
it.
Although some channels are more suitable
than others for displaying as webtops, you can display any channel or web
site as a webtop.
Follow these steps to set a channel as a
webtop:
-
If you haven't already done so, add the channel to My Channels.
-
Click Options at the bottom of the Netcaster window.
-
Select a site from the list.
-
Click the Properties button.
-
In the Properties dialog box, click the Display tab.
-
Select Webtop Mode.
-
Click OK.
Opening a webtop
-
Click My Channels in Netcaster. Channels that
can run as webtops have a small square webtop indicator located to the
right of the channel's name. When a channel is running as a webtop, its
webtop indicator glows.
-
Click the webtop you want to open. As the webtop
opens, it appears in front of all other windows for a few seconds before
moving behind, becoming the backmost window on your screen. When a webtop
is open, a Netscape "N" logo appears in the lower- right screen, and webtop
controls appear below it.
Changing webtops
-
Open My Channels and select the webtop you want to open. The new webtop
appears and replaces the previous one.
Hiding and showing a webtop
-
To hide a webtop, click the Desktop/Webtop button (small square with outline)
in the Netcaster window, or at the bottom of the webtop window.
-
To display the webtop again, click Desktop/Webtop again.
Closing a webtop
-
Click the Close Webtop button either in Netcaster or at the bottom of the
webtop itself.
Viewing a site while you're offline
You can use Netscape Netcaster to automatically download
any web site so that you can view it when you're offline (disconnected
from the Internet). Using a portable computer, you can browse a favorite
web site while you're away from your desk or when traveling, or anytime
when it's not convenient to establish a network connection. Because Netcaster
stores the web site on your computer's hard disk, you can browse the site
without the delays sometimes associated with browsing a site while connected.
If you're charged for connect time, viewing a web site offline can reduce
the cost of your Internet connection.
Before you can view a site offline, Netcaster
must download or update the site at least once. When Netcaster downloads
or updates a site, it stores the site's content on your hard disk.
Netcaster automatically downloads a site
when you do one of the following while you're online (connected to the
Internet):
-
Start Netcaster for the first time.
-
Add a site to My Channels.
-
In the Channel Properties dialog box, select the site you want to update
and click the Update Now button.
-
Right-click (Windows) or Ctrl-click (Macintosh) a site's link in Netcaster,
then choose Update from the menu that appears.
Setting download options
Netcaster can automatically download a site according
to a schedule that you specify. By regularly downloading a site, Netcaster
updates the site for you so that you always have the most current information.
You can control whether or not Netcaster
downloads a site, how often Netcaster downloads a site, how much of a site
Netcaster downloads, and how much disk space (cache size) you want to allocate
for the site.
Follow these steps to set a site's download
options:
-
Click Options at the bottom of the Netcaster window.
-
Select a site from the list.
-
Click the Properties button.
-
In the General panel, make sure that the checkbox is selected next to "Update
this channel or site."
-
Enter the update frequency.
-
Enter a time for the download.
-
Click the Cache tab.
-
Enter the number of levels you want Netcaster to download. One
level downloads the site's main page. Two levels includes the pages that
the main page links to. Three levels includes the pages that the second-
level pages link to. The more levels you download, the more room the site
occupies in its cache on your hard disk.
-
Enter the size (in kilobytes) you want to allocate for the site's disk
cache. Each site uses its own disk cache, which
takes up room on your hard disk. Most sites specify a cache size that you
can adjust lower if you have limited hard disk space, or higher if the
site is too large to fit in its cache.
-
Click OK.
Clearing the disk cache
To clear a site's disk cache and erase its content from your
hard disk:
-
Click Options at the bottom of the Netcaster window.
-
Select the site.
-
Click the Properties button.
-
Click the Cache tab.
-
Click Clear Cache.
-
Click OK.
Working offline
-
To disconnect and work offline in Communicator, open Navigator or Messenger
and choose Go Offline from the File menu.
If you're working offline when Netcaster is scheduled
to download a site, Netcaster doesn't download the site until the next
time you're connected and a download is scheduled to occur. If you're in
online mode but are not connected to the Internet (you haven't chosen Go
Offline but you've disconnected in another way), Netcaster attempts to
connect and complete a scheduled download.
Viewing a site offline
Follow these steps to view a site while not connected:
-
Make sure that Netcaster has downloaded the site at least once.
-
Start Netcaster.
-
Open My Channels.
-
Click the site's link.
Exiting Netcaster
-
Click Exit near the bottom of the Netcaster window. If you have a webtop
open, clicking Exit also closes the webtop.
