How the Gateway Works (With Real Examples)"},"content":{"rendered":"

A backconnect proxy gives you one address to connect to and a large pool of IPs behind it. You send every request to the same gateway. The gateway picks the exit IP for you.<\/p>\n\n\n\n

That solves a common problem. A single IP gets rate-limited after a few hundred requests. A long list of proxies works, but you have to rotate it, test it and replace dead IPs yourself. That stops scaling fast.<\/p>\n\n\n\n

This guide explains how backconnect proxies work, how rotating and sticky sessions differ, and whether a backconnect proxy is the same as a rotating proxy. Every concept is shown on a real gateway, the one NodeMaven uses for its residential and mobile proxies. You can copy the examples and test them yourself.<\/p>\n\n\n

What is a backconnect proxy?<\/h2>\n\n\n\n

A backconnect proxy is a proxy server that works as a single gateway to a pool of IP addresses.<\/strong> You connect to one host and port. The gateway sends each request through an exit IP from the pool and rotates or holds that IP based on your settings.<\/p>\n\n\n\n

The term describes how you connect, not where the IPs come from. Behind the gateway there can be residential, mobile, datacenter or ISP addresses.<\/p>\n\n\n\n

Backconnect proxies exist because some IPs are impossible to hand out as a list. Residential and mobile IPs belong to real devices. They go online and offline all the time. A static list would be out of date within minutes. A gateway hides that churn. It always knows which IPs are live and sends your traffic through one of them.<\/p>\n\n\n\n

Here is how a backconnect proxy compares to a classic proxy list.<\/p>\n\n\n\n

Backconnect proxy vs reverse proxy<\/h3>\n\n\n\n

The names sound similar, but the tools work in opposite directions<\/strong>. A backconnect proxy is a forward proxy. It acts for you, the client, and hides your IP from the websites you visit. A reverse proxy sits in front of a website’s servers and protects them from visitors. If you run a scraper or manage accounts, you need the first one. You can read more in our guide to reverse proxies<\/a>.<\/p>\n\n\n\n

How a backconnect proxy network works<\/h2>\n\n\n\n

Every request through a backconnect proxy network follows the same path.<\/p>\n\n\n\n

    \n
  1. Your app sends the request<\/strong> to the gateway address. This address never changes.<\/li>\n\n\n\n
  2. The gateway reads your settings<\/strong> from the proxy username. That includes location, session type and IP quality level.<\/li>\n\n\n\n
  3. It picks a matching exit IP<\/strong> from the pool.<\/li>\n\n\n\n
  4. \u8be5 request reaches the target website<\/strong> from that IP.<\/li>\n\n\n\n
  5. \u8be5 response travels back<\/strong> through the same gateway to your app.<\/li>\n<\/ol>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    Your code never sees the pool. You do not track which IPs are burned or cooling down. The gateway does that in the background. That is the main reason backconnect proxies replaced manual proxy lists for most large projects.<\/p>\n\n\n\n

    Real example: reading a NodeMaven backconnect proxy string<\/h2>\n\n\n\n

    All NodeMaven residential and mobile proxies go through one gateway. Here is what a connection looks like.<\/p>\n\n\n
