About the proxy chaining plugin

You can use the proxy chaining plugin with a McAfee Web Gateway appliance as an upstream proxy

server for content and URL filtering, or with the McAfee SaaS Web Protection service for URL filtering.

• McAfee Web Gateway — Use the McAfee Web Gateway appliance as an upstream proxy server in

your proxy chain environment to analyze web traffic and apply filters to URLs or content, which

adds security against web-based threats. When you use the McAfee Web Gateway appliance as an

upstream proxy, the proxy chaining plugin forwards web traffic requests that are passing through

your network to the McAfee Web Gateway appliance. When the web traffic reaches the appliance,

policies you have set up are applied to the requests and then the URLs or content is either allowed

or blocked.

• McAfee SaaS Web Protection — Use the McAfee SaaS Web Protection service as an upstream proxy

server in your proxy chain environment to analyze URLs in web traffic requests. The proxy chaining

plugin forwards web traffic requests to the the McAfee SaaS Web Protection service, where the

URLs are identified and either allowed or blocked according to the policies and rules you have set up.

The McAfee Web Gateway appliance or McAfee SaaS Web Protection service adds security for web

traffic, and the Microsoft ISA Server handles the remaining network traffic.

If you have caching enabled on the Microsoft ISA Server and user-based policies set up on the McAfee

Web Gateway appliance or the McAfee SaaS Web Protection service, all requests might not be forwarded

for additional filtering. Because of this, when you enable user-based policies on the McAfee Web

Gateway appliance or McAfee SaaS Web Protection service, you should disable caching on the Microsoft

ISA Server.
