How Reverse Proxies Work: Reverse Proxy Technology Explained

What the hell is a reverse proxy?

Let's take a courier cabinet chestnut. Normally, online shopping packages are not delivered directly to your doorstep, but are placed in the neighborhood courier locker. Reverse proxy to do this job - it sits in front of the server, to help the real server to receive requests. Users will always see the "courier cabinet", do not know the back of who is actually dealing with the request.

There's a big advantage to using a proxy IP for reverse proxying:Real server IPs are completely invisibleThe real thing is that it's not the real thing, it's the real thing. Just like a star using a body double to shoot a movie, the paparazzi photographed the body double, the real body early slipped through the back door. Especially when doing data collection, this trick can effectively avoid the target site seal your real address.

Three steps to figure out how to run a reverse proxy

1. Request Interception: the user first hits a reverse proxy server (e.g. a node built with ipipgo's static residential IP)
2. Intelligent forwarding: The proxy forwards the request to the corresponding server based on preset rules (geography, traffic, type of business).
3. Results ReturnsAfter getting the response from the server, the proxy will also "make up" the data (e.g., encrypt/compress it) and return it to the user.

Here's a key point:Proxy IP quality directly determines forwarding efficiency. Customers who have used ipipgo know that the latency of their TK line can be pressed down to less than 50ms, which is more than three times faster than ordinary agents.

 Example of fast proxy fetching with the ipipgo API
import requests

api_url = "https://api.ipipgo.com/getproxy"
params = {
    "key": "Your API key",
    "type": "static", static home type
    "count": 1
}
response = requests.get(api_url, params=params)
proxy = response.json()['data'][0]
print(f "Getting proxy: {proxy['ip']}:{proxy['port']}")

Which scenarios must be on a reverse proxy?

A must-have for veteran reptile drivers:When doing large-scale data collection, the combination of reverse proxy + dynamic IP pool can make the target website think that it is visited by different users. There is a customer doing e-commerce price comparison, after using ipipgo's dynamic residential package, the IP blocking rate dropped from 70% to less than 5%.

Privacy protection is just needed:In sensitive industries such as healthcare and finance, reverse proxy can isolate the direct contact between users and internal systems. Previously, a P2P platform was attacked, and then on the ipipgo cross-border line, the attack traffic directly to the empty IP.

QA Time: Common Pitfalls for Newbies

Q: How do I choose between dynamic and static residential IPs?
A: Frequent change of business choose dynamic (such as 7.67 yuan / GB of the standard package), fixed business with static (35 yuan / IP). There is a misunderstanding to be corrected - not the more expensive the better, do CAPTCHA recognition instead of using dynamic IP.

Q: Why is the proxy slow sometimes?
A: It's probably because you didn't choose the right protocol. For video transmission, you should use Socks5, but for general webpage, you can use HTTP. ipipgo client has an intelligent protocol switching function, which can automatically match the best mode.

How do you hitch a ride with a reliable reverse proxy?

Here's a recommendation from ipipgoEnterprise Dynamic Package($9.47/GB) in favor of three strokes:
1. Automatic load balancing: traffic will automatically allocate multiple IP channels
2. Failure second switching: an IP is blocked immediately enable the backup line
3. Traffic reuse: the connection has been established can be reused, saving 20% more than traffic

The configuration trick is totriage strategyThe following are some of the reasons for this. The image requests are divided into data center IPs, and the API requests are divided into residential IPs. this saves money and is stable, a cross-border e-commerce customer uses this trick, and saves more than 40,000 yuan in agent costs per month.

Lastly, I'd like to say a few words: don't just look at the price when choosing a proxy service. ipipgo can provide 1v1 program customization which is quite real, last time there was an overseas questionnaire team, and their customized program directly pulls the success rate from 23% to 68%, which is really something.
