How to combine Fiddler and Privoxy?

[Heck Lennon]

Hello

I need to run Fiddler and Privoxy, so that I see what Chrome sends to the web server:

Browser <-> Privoxy <-> Fiddler <-> web server

As a privacy measure, I want to use Privoxy to remove most infos sent by the browser.

It seems like Fiddler will set itself up as the only proxy: When it's ran, Privoxy is out of the picture, even after configuring Chrome to use "127.0.0.1:8118" so it first goes through Privoxy.

Can Fiddler and Privoxy play nice together?

Thank you.

1. Close Fiddler.

2. Set your Internet Explorer settings to point at Privoxy (Tools > Internet Options > Connections > LAN Settings).

3. Start Fiddler.

 

Fiddler will chain to the existing proxy, so the network flow would be Chrome -> Fiddler -> Privoxy -> Internet.

 

If your goal is to have the flow be Chrome -> Privoxy -> Fiddler -> Internet, then:

 

1. Close Fiddler.

2. Ensure that the browser's proxy settings are empty / no proxy.

3. Start fiddler.exe -noattach

4. Configure Privoxy so that its upstream/parent/forward server is 127.0.0.1:8888. See http://unix.stackexchange.com/questions/20907/how-to-use-a-proxy-when-using-privoxy

5. Configure your browser to use Privoxy

 

If you do it this way, Chrome will talk to Privoxy which will talk to Fiddler which will talk to the Internet.
