Introduction

If Internet requests are not transparently routed to Content Gateway via a Layer 4 switch or router (see Transparent Proxy and ARM), traffic must be explicitly routed to Content Gateway by configuring the client’s Internet browser. (This is sometimes referred to as an explicit proxy deployment.)

Clients can configure their web browsers in 1 of 3 ways:

• By directly configuring their browsers to send requests directly to the proxy. See Manual browser configuration.
• By configuring their browsers to download proxy configuration instructions from a proxy auto-config (PAC) file. See Using a PAC file.
• By using Web Proxy Auto-Discovery Protocol (WPAD) to download proxy configuration instructions from a WPAD server (Microsoft Internet Explorer only). See Using WPAD.

In addition, if Content Gateway is configured to proxy FTP traffic, FTP client applications, such as FileZilla or WS_FTP, must be configured to explicitly send requests to the proxy. See Configuring FTP clients in an explicit proxy environment.
