What is Proxy?

A proxy server acts as an intermediary for requests between a client and a server. In simple terms, the traffic flows through the proxy server on its way to the address you requested and back.

A proxy server for automation scripts with Selenium could be helpful for:

• Capture network traffic
• Mock backend calls made by the website
• Access the required website under complex network topologies or strict corporate restrictions/policies.

1. Create an instance of FirefoxOptions

FirefoxOptions options = new FirefoxOptions();

2. Set the desired preferences or proxy configuration

Create an instance of ChromeOptions and set the proxy:

options.addPreference("network.proxy.type", 1);
options.addPreference("network.proxy.http", proxyAddress);
options.addPreference("network.proxy.http_port", proxyPort);

Replace “proxyAddress” with your actual proxy address and “proxyPort“ with the appropriate port number.

 network.proxy.type is a preference that determines the type of proxy being used. It is a configuration option that can be set to different values to specify the proxy type.

The possible values for network.proxy.type are:

– 0: Direct connection (no proxy)
– 1: Manual proxy configuration
– 2: Proxy auto-configuration (PAC)
– 4: Auto-detect proxy settings

Launch Firefox WebDriver with the configured options:

driver = new FirefoxDriver(options);

The complete program is mentioned below:

package org.example;

import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;

public class FireFoxProxyDemo {


    public static void main(String[] args) {

        // Set the proxy server details
        String proxyAddress = "localhost";
        int proxyPort = 8080;
        FirefoxDriver driver;

        // Create an instance of `FirefoxOptions` and set the proxy configuration
        FirefoxOptions options = new FirefoxOptions();
        options.addPreference("network.proxy.type", 1);
        options.addPreference("network.proxy.http", proxyAddress);
        options.addPreference("network.proxy.http_port", proxyPort);

        // Instantiate FireFox Driver with the configured options
         driver = new FirefoxDriver(options);

        // Perform your browsing actions using the driver
        driver.get("https://www.google.com");
        System.out.println("Page Title :" + driver.getTitle());

        // Close the browser session
        driver.quit();
    }
}

The output of the above program is
