BackWeb Version 2.0
============================================================================
For the latest information see http://www.backweb.com.
============================================================================
Introduction - Let Information Find You for a Change
============================================================================
Labor intensive Web surfing is being replaced by the information
intensive approach of BackWeb. Let your computer and the Internet
do the work for you for a change.
Install BackWeb today and you'll be on your way to getting personalized
information, entertainment, and software from the Internet, all delivered
automatically to your desktop. BackWeb makes this possible by sending
software and data to you in the background, taking advantage of your
Internet connection's idle time while you're connected to the net.
This means you no longer have to wait for long downloads or go out and
search for information. You subscribe to the channels you're interested
in once and from then on information is automatically delivered to you.
This README file includes the following topics:
A. System Requirements
B. Installation Instructions
C. Uninstalling BackWeb
D. Subscribing to BackWeb Channels
E. Important note regarding Internet Connection and Communication
F. Known issues that may affect some users
G. Technical Support
============================================================================
A. System Requirements
============================================================================
Operating System: Windows 95 or Windows NT 4.0
(Version 1.2 is available for Windows 3.11)
Minimum Hardware: 486 66MHz, 16MB RAM
Disk Space: 4MB for the BackWeb software and 6MB per channel (user
configurable)
Internet Connection: Either direct connection or 14.4 Kbps Modem or higher
Web browser: Either Netscape Navigator 2.0 or higher or Microsoft
Explorer 2.0 or higher
============================================================================
B. Installation
============================================================================
If you do not have the BackWeb CD, see http://www.backweb.com
for download and installation instructions.
Before you begin, make sure you are running Windows 95 or Windows NT 4.0.
1. In the CD drive, change directory to \CLIENT\WIN95\SETUP.
2. Double-click the SETUP.EXE file to install BackWeb on your computer.
3. Following installation, BackWeb is launched and you are taken on a
"guided tour" of the system where you can go through Quick Setup steps
to customize BackWeb to meet your specific needs.
Quick Setup enables you to:
* View and interact with a sample InfoPak.
* Specify whether InfoPaks should be automatically or manually played.
* Register to channels of your choice from a Channel Directory.
* Specify the maximum amount of disk space per channel that you wish
to allow for the storage of InfoPaks.
============================================================================
C. Uninstalling BackWeb
============================================================================
1. In your system Control Panel, launch Add/Remove Programs.
2. Choose BackWeb from the list.
3. Click Add/Remove to uninstall BackWeb.
============================================================================
D. Subscribing to BackWeb Channels
============================================================================
Once you have installed BackWeb, you need to subscribe to "channels" to
receive information with your BackWeb software.
Go to the BackWeb Web site (http://www.backweb.com/) to subscribe to the
wide range of channels or sources of information that interest you. This
subscription process is done through the Web. After that, you will receive
the information from these channels via BackWeb.
============================================================================
E. Internet Connection and Communication
============================================================================
The following is relevant to users who are connected to the Internet
via a corporate network (LAN) and corporate firewall. It is also relevant
to users who are connected to the Internet via an online service. In
both of these cases, there is a possibility that your Internet connection
(either because of the corporate firewall configuration or because of
the way the online service communicates with the Internet) does not
support the standard communication protocol called UDP. If this is
the case, your BackWeb software will not communicate over the network
using the Polite Agent mode.
This version of BackWeb introduces the option to have BackWeb communicate
with another standard communication protocol called HTTP. This will allow
anyone with an Internet connection to use BackWeb, regardless of
corporate firewalls or online services.
It is recommended that you use the Polite Agent mode if possible,
as it offers substantial benefits to users - it allows the background
communication to happen in an unobtrusive, discreet way. HTTP is
not as "polite," and you will sometimes notice it working even though
BackWeb is running in the background.
This note is only relevant if you want to use the Polite Agent
mode even though you are behind a corporate firewall:
By default, BackWeb requires that your corporate firewall allows UDP
packets with destination port 370 to go out from your network to the
Internet, and UDP packets with destination port 371 to come in from the
Internet to your network.
You can select the UDP port through which BackWeb will connect to the
Internet from the Advanced Settings dialog in the Connection tab of the
Setup dialog.
============================================================================
F. Known Issues
============================================================================
1. BackWeb software configures your browser to include a registration
helper application. If for some reason this setting is missing, you may
enable channel registration via Web sites by the following steps.
If you are using Netscape Navigator:
Launch the browser and select General Preferences in the Options menu.
Click the Helpers tab and Create New Type. Enter 'application' in the
Mime Type field and 'x-iad' in the Mime Sub Type field. Enter 'iad' in
the File Extensions field. Select the radio button "Launch the
Application", and browse for register.exe in the BackWeb program folder.
The default location is "C:\Program Files\BackWeb\BackWeb\program".
Click OK to close the dialog.
If you are using Microsoft Internet Explorer:
Launch the browser and open the Options dialog in the view menu.
Click the File Types tab.
Click the New Type button. Fill in the following values in the
corresponding fields.
Description of type: BackWeb Registration
Associated extension: .iad
Content type (MIME): application/x-iad
Default Extension: .iad
Make sure to uncheck Confirm Open After Download.
Click the New button to open the New Action Dialog. Enter 'open' in
the Action field. Browse for register.exe in the BackWeb program folder.
The default location is "C:\Program Files\BackWeb\BackWeb\program".
Click OK to close the dialog. Close the parent dialogs by clicking the
Close button.
If you are using a different browser, you may look for the instructions
on how to associate actions with MIME types and extensions. Associate
MIME type application/x-iad and the extension .iad with the program
"C:\Program Files\BackWeb\BackWeb\program\register.exe".
2. In some cases where the Netscape browser was unable to locate the
server of the given URL, it becomes impossible to invoke Web pages from
BackWeb. In order to continue, click the OK button in the Netscape
window to close the "Unable to locate server <URL>" message box.
3. Plug-in applications launched from InfoPaks may produce sound even
when the InfoPak is muted.
4. If you have installed a plug-in or QuickTime / QuickTime VR software
during the current BackWeb session, you still may not receive InfoPaks
that require these plug-ins. In order to recognize the installed plug-ins,
shut down BackWeb (from the File menu) and re-launch BackWeb using the
system Start button. Alternatively, you may restart your system so that
BackWeb will be automatically re-launched.
5. After installing Microsoft Java VM, you must restart your system prior
to playing InfoPaks that include Java applets.
6. Under Windows NT 4.0, BackWeb does not allow interaction with screen
saver InfoPaks. The Interaction group in the Screen Saver tab of the
Global Options is therefore grayed out.
If you wish to interact with a BackWeb screen saver (that's designed to
support interaction), you may play it manually from within the BackWeb
Window. This will give it the appearance of a screen saver but the
properties of a Flash, which can be interacted with.
7. If you use the Netscape browser, we recommend that you do not include the
executable in your StartUp folder. Every time that BackWeb starts up, it
makes sure that Netscape is set up properly allowing you to add BackWeb
channels. However, due to the way Netscape works, this verification is
only effective when Netscape is not running.
If you have Netscape in the StartUp folder, it is quite possible that
Netscape will already be running every time that BackWeb starts up, and
the set-up routine required for adding BackWeb channels will not take
place.
If you must put Netscape in the start-up folder, you can make sure that
the set-up is done properly at least once by manually shutting down both
Netscape and BackWeb (by choosing Shut Down BackWeb on BackWeb's File
menu), then restarting BackWeb and then Netscape. You should then try
registering to a new channel (via Add Channel using Web Directory on
BackWeb's Channel menu) to make sure everything is working properly.
8. If you invoke Netscape Gold version 2.02 via the BackWeb interface (or
by interacting with an InfoFlash) and the browser is already active,
BackWeb might not bring the browser window into focus. You may use
<Alt>-TAB to focus on the browser's window.
9. If you are using Internet Explorer 2.0, you may encounter problems
registering with some BackWeb channels where the CGI script generates
a file of an extension different than '.iad'.
This problem occurs when Internet Explorer 2.0 looks for a helper
application based on the file extension rather than the MIME type
provided (application/x-iad). For example, if the CGI script which
prepares the channel registration data is a perl script whose name
is 'xxx.pl', then the IE 2.0 looks for a program which is associated
with the extension '.pl' instead of using the given MIME type.
To work around this problem, use the "Save As" option to save the
registration file in your disk with the extension '.iad'. Double-click
the saved file to register with the channel
10. Note that you might experience problems receiving InfoPaks from some
of the channels if you configured BackWeb to work with HTTP (with or
without an HTTP proxy).
BackWeb Technologies is doing its best to make sure all the channels are
using the latest version of the BackWeb channel server which supports a
wide range of HTTP proxies.
