What rotating proxies are and how the gateway works
A rotating proxy is a single front-door endpoint, often called a backconnect gateway, that sits in front of a large pool of IP addresses. Your client always connects to the same host and port, but the gateway maps each outbound request to a different address drawn from the pool. The result is that the destination website sees many distinct IPs over time even though your software only knows about one.
Two things happen on every request. First, the gateway authenticates you, either by your username and password or by checking your IP against a whitelist. Second, it selects an exit address according to the rotation rule attached to your session: a new IP per request, or the same IP held for a set window. Because the pool membership and selection logic live on our side, you get the benefit of address diversity without managing a list of individual proxies, rebuilding it as IPs age out, or load-balancing between them yourself.
