Today I’d like to talk about how to configure ZA Proxy for intercepting HTTP request in localhost.

Installation

Configuration

Ensure both ZA Proxy and Firefox use the same port for proxy. I’m using :18080 here:

  • In ZA Proxy, change the port used in Tools » Options » Local Proxies
  • In Firefox, configure the proxy via Connection Settings. Use “manual proxy configuration” with the following properties:
Property Value
HTTP Proxy localhost
HTTP Proxy port 18080
Use this proxy server for all protocals yes

Intercept HTTP

Now, you can intercept the HTTP traffic in ZA Proxy.
