Can you insert additional headers into HTTP requests when using WebDriver?

The standard WebDriver API does not provide a direct way to add or modify HTTP request headers sent by the browser during navigation or actions.

This is because WebDriver operates at the level of browser interaction, not at the network traffic level.

However, there are workarounds:

• Use a proxy server (e.g., BrowserMob Proxy) that intercepts and modifies HTTP requests.
• In some browsers (e.g., Chrome), you can use extensions or the DevTools Protocol to change headers.
• In ChromeDriver, you can use the CDP (Chrome DevTools Protocol) to set headers via commands.

An example using CDP in Go (via chromedp) or JavaScript allows adding headers, but this goes beyond the standard WebDriver.

Thus, directly through WebDriver — it's not possible, but with additional tools and configurations — it is.
