The website for BFilter states the following as a feature:

Forwarding to another proxy (HTTP and SOCKS proxies).

However, nowhere on the site, in the FAQ or in the documentation, are you told how to do this. Really annoying. If you’re going to list features and provide documentation, document how to use the features!

I figured out how to use this feature by accident in Mac OS X. When you install BFilter, it creates new network profiles that specifically enable filtering. For instance, if you have a network profile named “Home”, BFilter creates a profile named “(BF) Home”. Selecting that profile proxies your HTTP traffic through the BFilter software.

To enable another proxy, such as a caching proxy, you need to edit the original”home” (or whatever) profile and set the proxy for that profile to the caching server. For example:

Profile: (BF) Home
Proxy: 127.0.0.1:8080

Profile: Home
Proxy: 192.168.1.254:8000

That will route HTTP traffic through both the caching proxy and the ad filtering proxy. Good stuff.
