We recently needed to implement a headless browser (used Selenium). It was required to send requests from different Ip addresses without restarting the driver, but after searching the Internet for information, I did not find a way to do this without restarting.
A few days later we found a solution, I want to share it by answering my own question.
We have a server with a set of external ip. We will raise the proxy to our own on the locale.
We used 3Proxy to run our proxies.
Variation 1: When initializing the driver, we can choose a local ip and port as a proxy. Thus, to change the ip, we only need to restart the proxy on this port, which will refer to another ip.
Variation 2: If you want to use a proxy that is not raised by you, then you can modify the solution, create a proxy chain.
Your browser will access the local address where you will raise a proxy that will forward the request to the desired proxy. So to change the proxy, you will need to restart the local proxy, which performs the function of a router between your ChromeDriver and the target proxy (it may be a free proxy that is not connected to you in any way), which remains unchanged.
It's like with the arrows on the railway.
