I develop a web scraping project using Selenium. Since I need rotating proxies [in mass quantities] to be utilized in the project, I’ve turned to the proxy gateways (nohodo.com, charityengine.com and some others). The problem is how to incorporate those proxy gateways into Selenium for surfing web?

What I already am aware of:

Selenium using a single proxy IP, yet at Remote WebDriver

source

Python code to accomodate proxy gateway

So, how to join both Selenium and a proxy gateway?
