3 Proxies and caching Contents Intercepting web traffic Network modes Common proxy settings Reverse HTTPS proxy configuration Providing proxy auto-configuration files Helix proxy configuration Preventing data leaks Web caching Intercepting web traffic The McAfee Web Gateway appliance is installed as a gateway that intercepts and filters web traffic to ensure web security for your network. It does this in explicit proxy mode or in transparent mode, using particular network protocols. The sections of this chapter tell you how to configure the use of network modes and protocols. They also tell you how to configure the web cache, which stores frequently requested objects locally to speed up browsing. Proxy settings You can review and modify the settings for the proxy functions on the Appliances tab of the Configuration top-level menu under Proxies (HTTP(S), FTP, ICAP, and IM). After the initial setup, these settings have preconfigured values. The most important are: • Network mode — Explicit proxy • Network protocol — HTTP If you keep the explicit proxy mode, you need to configure the clients of the appliance, so that they direct their requests for web access to it. This applies also to a proxy-chain configuration when the appliance is not immediately connected to a client. If you modify the preconfigured settings, you might not need to configure clients in this way, but other network components that are then involved. For more information, see Network modes and Common proxy settings. McAfee Web Gateway 7.1.5 Product Guide 37
