Siebel Client Deployment Requirements When Using Firewalls or Proxy Servers

This section describes Siebel client deployment requirements that apply when you use firewalls or proxy servers (such as reverse proxy servers).

Deploying Siebel Applications Accessed Through a Firewall

When deploying Siebel applications accessed through a firewall, verify that your firewall supports the HTTP 1.1 protocol, if you are planning to enable compression for traffic between the Web server and the Web browser. This issue applies to both standard-interactivity and high-interactivity applications.

If your firewall does not support HTTP 1.1, set the DoCompression parameter appropriately in the eapps.cfg file on the SWSE. In addition, for high-interactivity applications, specify the Internet Explorer setting to disable HTTP 1.1 for proxy connections on each client machine, as described below.

NOTE:  For more information about deploying Siebel applications with firewalls, and about settings for the DoCompression parameter, see Security Guide for Siebel eBusiness Applications.

To specify Internet Explorer settings to disable using HTTP 1.1 through a proxy

1. In Internet Explorer, choose Tools > Internet Options.
2. Click the Advanced tab.
3. Under HTTP 1.1 settings, uncheck Use HTTP 1.1 through proxy connections.
4. Click OK.

Bypassing the Proxy Server for Local Addresses—for High-Interactivity Applications

If your LAN network uses a proxy server, Internet Explorer browser settings should be adjusted to bypass the proxy server for local (internal) addresses. This setting provides better performance for all Siebel clients described in this book, for high-interactivity applications deployed on the LAN. This setting is required for the Siebel Mobile or Dedicated Web Client.

NOTE:  For standard-interactivity applications, this setting does not apply. The proxy server setting applies only on a LAN.

To specify Internet Explorer settings to bypass the proxy server for local addresses

1. In Internet Explorer, choose Tools > Internet Options.
2. Click the Connections tab, then click the LAN Settings button.
3. In the Proxy server section, verify whether the option Use a Proxy server for your LAN is enabled.

   For Siebel Web Clients running employee applications, where a proxy server is provided on a LAN, the proxy server address and port would also be specified here.

4. If the option Use a Proxy server for your LAN is enabled, check the box for Bypass proxy server for local addresses.
5. Click OK, then click OK again.
