CLI HTTPS usage

To make fake-corp-proxy to handle HTTPS protocol, you need to generate a CA certificate:

fake-corp-proxy-ca root my-ca-name

Then, you have to trust the generated certificate on your OS (More infos).

Once your CA certificate is trusted you can tunnel HTTPS requests to your proxy. You can also run the proxy in HTTPS mode.

fake-corp-proxy --https

If you forget where is stored you CA certificate, you can run:

fake-corp-proxy-ca root-path

Module usage

Simple usage:

const fakeProxy = require("fake-corp-proxy");
 
// Start server
const server = fakeProxy.start({
    port: 8080,
    ntlm: true
});
 
// When finished
server.close();

*Note: The same options as CLI are available"

Proxy Auto-Configuration (PAC Script)

This Proxy supports PAC Script generation:

curl http://localhost:8080/pac

Simulate Authentication errors

This module does not really authenticate users. To simulate an unauthorized user, just use a username starting with unknwown. (eg: unkwnown, unkwnown-user, unkwnown-test)

curl --proxy-insecure -x \"https://unknown:password@localhost:8081\" https://www.google.com/
