In this post, let’s talk about how to handle proxy setting using selenium Webdriver?
While setting up the proxy, note that there are different values for network.proxy.type , which we need to set based on our need. Here are some values –
0 – Direct connection (or) no proxy.
1 – Manual proxy configuration
2 – Proxy auto-configuration (PAC).
4 – Auto-detect proxy settings.
5 – Use system proxy settings.
Below 4 steps explain how can we handle proxy setting via selenium
Step1: Create the FirefoxProfile object.
Step2: Set preference for network.proxy.type
Step3: Set preference for network.proxy.http
Step4: network.proxy.http_port
    FirefoxProfile profile = new FirefoxProfile();

    profile.setPreference("network.proxy.type", 1);

    profile.setPreference("network.proxy.http", "proxy.domain.example.com");

    profile.setPreference("network.proxy.http_port", 8080);

    profile.setPreference("network.proxy.ssl", "proxy.domain.example.com");

    profile.setPreference("network.proxy.ssl_port", 8080);

    WebDriver driver = new FirefoxDriver(profile);

That’s it, this should handle the updated proxy in code.
