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, if you are planning to enable compression for traffic between the Web server and the Web browser, your firewall must support the HTTP 1.1 protocol. This issue applies to both standard-interactivity and high-interactivity applications.

If your firewall does not support HTTP 1.1, set the DoCompression parameter to FALSE in the eapps.cfg file on the Siebel Web Server Extension (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 Siebel Security Guide.

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

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 for High Interactivity Applications

If your LAN network uses a proxy server, adjust your Internet Explorer browser settings to bypass the proxy server for local (internal) addresses. This setting provides better performance for all Siebel clients described in this chapter and for high-interactivity applications deployed on the LAN. This setting is required for the Siebel Mobile 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. 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, specify the proxy server address and port number 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.
