Siebel Client Deployment Requirements When Using Firewalls or Proxy Servers

This topic describes Siebel client deployment requirements that apply when you use firewalls or proxy servers, such as reverse proxy servers. This topic applies to all Siebel applications that are deployed inside the firewall or using a proxy server.

Deploying Siebel Business Applications Accessed Through a Firewall

When deploying Siebel Business Applications that are accessed through a firewall, if you are planning to enable compression for traffic between the Web server and the Web browser, then your firewall must support the HTTP 1.1 protocol.

If your firewall does not support HTTP 1.1, then set the DoCompression parameter to False in the eapps.cfg file on the Siebel Web Server Extension (SWSE). In addition, disable HTTP 1.1 for proxy connections on each client computer. This procedure describes how to configure Microsoft Internet Explorer for this purpose.

NOTE:  For more information about deploying Siebel Business Applications with firewalls, and about settings for the DoCompression parameter, see Siebel Security Hardening Guide, Siebel Security Guide, and the Siebel Installation Guide for the operating system you are using. See also the description of the DoCompression parameter in Parameter Descriptions of the eapps.cfg File.

To specify Internet Explorer settings to disable HTTP 1.1 for proxy connections

1. From the Internet Explorer Tools menu, choose 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

If your LAN uses a proxy server, then adjust your browser settings to bypass the proxy server for local (internal) addresses. This setting provides better performance for Siebel employee applications deployed on the LAN, and is required for the Siebel Mobile Web Client. This procedure describes how to configure Microsoft Internet Explorer for this purpose.

NOTE:  For customer 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. From the Internet Explorer Tools menu, choose 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, also specify the proxy server address and port number.

4. If the option Use a Proxy Server for Your LAN is enabled, then check the box for Bypass Proxy Server for Local Addresses.
5. Click OK, then click OK again.
