Default.
You can also use the Connections tab to configure proxy server settings. A proxy server
is a centralized network device that provides Internet access to the client computers on
the network, as shown in Figure 16-19. Proxy servers are used to centralize Internet
connection settings, increase security by controlling which resources a client can
access, and speed up Internet access by caching Web pages to the server. After you
configure Internet Explorer to use a proxy server, Internet Explorer requests Internet
content from the proxy server, which in turn connects to the actual Internet resource
on the client’s behalf, retrieves the information, and forwards it to the client.

To configure Internet Explorer to use a proxy server for dial-up and VPN connections,
select the connection, and then click Settings. To configure Internet Explorer to use a
proxy server for local area network (LAN) connections, click LAN Settings.
Figure 16-20 shows the available proxy server configuration options, which are as follows:
Automatically Detect Settings Allows the client to automatically receive proxy
server configuration from a properly configured Dynamic Host Configuration Protocol
(DHCP) or Domain Name System (DNS) server.
Use Automatic Configuration Script Specifies the path to a configuration script
containing proxy server information.
Use A Proxy Server For This Connection Allows you to enter the address of the
proxy server and the port that Internet Explorer should use to connect to the
proxy server.
Bypass Proxy Server For Local Addresses Allows the client to connect directly to
address on the local network (such as an internal company Web server) instead of
connecting to the proxy server.
