Installation manual

where yourhostname and alias are your Host On-Demand Version 4.x server’s
hostname and alias, or Publish, directory. The HODServer parameter works with
the UpgradePercent and UpgradeURL parameters to manage client upgrades. If the
cached client won’t be upgraded on this connection attempt, it is redirected
automatically to the Host On-Demand Version 4.x server specified in the
HODServer HTML parameter. If a cached client will be upgraded, the Host
On-Demand Version 4.x cached client is removed and the Host On-Demand
Version 6 cached client is installed. Once the client is upgraded to Host
On-Demand Version 6, the HTML parameter is ignored and the client is no longer
redirected to the Host On-Demand Version 4.x server. After you have gradually
upgraded all your cached clients, you no longer need the Host On-Demand
Version 4.x server.
Notes:
v Cached clients are upgraded in the foreground. The upgrade in background
option is ignored.
v If you have customized Host On-Demand Version 4.x HODCached.html and have
called it something different, like OurHTML.html, you can:
– Copy the Host On-Demand Version 6 version of HODCached.html to the file
OurHTML.html;
– Then add the HODServer parameter to OurHTML.html. The HODServer parameter
should specify http://yourhostname/alias/OurHTML.html as the Host
On-Demand Version 4.x server.
v You can copy the new HODCached.html, that includes the HODServer parameter, to
AutoHODCached.html and AutoHODLaunch.html, in case these pages are
bookmarked by the clients. The HODServer parameter in AutoHODCached.html
should specify the AutoHODCached.html page on the Host On-Demand Version
4.x server. The HODServer parameter in AutoHODLaunch.html should specify the
AutoHODLaunch.html page on the Host On-Demand Version 4.x server
v If you are using language specific HTML pages (such as HODCached_es.html,
AutoHODCached_es.html, AutoHODLaunch_es.html, etc.) you can also add the
HODServer to these pages.
Troubleshooting
If you find that you cannot load the cached client, check the items described below.
Netscape 4.x:
1. In the browser window, click Edit > Preferences > Advanced.
2. Check Enable Java.
3. Check Enable JavaScript.
Microsoft Internet Explorer 4.0.1:
1. In the browser window, click View > Internet Options > Security.
2. Make sure that the Internet and Local Intranet zones are set to Medium
security.
Microsoft Internet Explorer 5.5: After upgrading your browser from Microsoft
Internet Explorer 4 to Microsoft Internet Explorer 5.5, you may receive security
exceptions in the Java console. When you install the Cached Client, several files are
stored into the browser’s directory structure. When you upgrade Internet Explorer
from Version 4 to Version 5, the browser will no longer know about the CAB files
which contain the Host On-Demand cached code. Since the browser cannot find
the CAB files, it tries to use the class files directly from the server, causing security
