Reverse Connection Proxy Technology White Paper

What the hell is a reverse connection proxy?

Recently, a friend always asked me, said in the data collection always be the target site blocked IP, this reverse connection proxy can not break? To put it simply, a reverse connection proxy is like putting aA shield that changes faces.Reverse proxy is a way for a website to come to you. Ordinary proxy is that you take the initiative to find the website, reverse proxy is to let the website take the initiative to find you. This trick is especially suitable for business scenarios that require long-term stable connections, such as automated data monitoring.

For example, let's use ipipgo'sLong-lasting Tunnel AgentDo test: the client first connects to the proxy server to establish a channel, then the target site to see the request is sent from the proxy server. Even if the target website opens the anti-climbing mechanism, the IP of the proxy server is also sealed, and the IP pool of ipipgo automatically replaces 5000+ addresses every day, so it can't be sealed at all.

Reverse proxy configuration in three minutes

Don't be intimidated by the technical terms, the actual operation is easier than you think:

The third step is where many newbies get stuck. ipipgo's system automatically generates theDynamic Authentication KeyIf you are not able to do so, remember to add this authentication parameter to your business code, otherwise it will be treated as an illegal connection and simply pinched off.

What are the pitfalls to avoid when choosing a service provider?

There are numerous agency service providers on the market, but not many of them are reliable. Three hard indicators must be met:

① IP survival time > 6 hours: short-lived proxies can't hold up to reverse connections!
②Concurrent channels ≥ 50: Below that, it tends to lag.
③Disconnection and reconnection <3 seconds: ipipgo's Smart Route Switching Tested 1.8 Second Recovery

Pay special attention to see if the service provider hasDedicated Client. Tools like TunnelMaster provided by ipipgo can automatically handle the hassles of certificate renewal and traffic encryption, saving you a lot of time and effort over writing your own scripts.

Guidelines for the clearance of operational problems

Q：Why can't I connect after successful configuration?
A: Ninety percent is a fire problem. First, use telnet to test the port pass or fail, if timeout, go to the server security group to release the corresponding port.

Q: What should I do if the data transfer suddenly slows down?
A: In the ipipgo background to switch the line area, it is recommended to prioritize the selection of theEast-South Chinaof transit nodes, the latency can drop around 40%.

Q: How can I prevent being recognized as proxy traffic?
A: Open the client'straffic camouflagefunction, the TCP request packets disguised as HTTPS traffic, pro-test effectively avoid 80% protocol detection.

How do enterprise solutions play out?

For large clients that need to handle millions of requests, it is recommended that ipipgo'sDistributed Agent ClusterProgram. Distribute requests to proxy nodes in different regions through load balancing, with intelligent scheduling algorithms to ensure that the request volume of each node is within the safety threshold.

Actual data measured by an e-commerce customer:
Single node daily request volume: 120,000 → 30,000 (down 75%)
Request Success Rate: 68% → 92%
Probability of IP blocking: 20 times per day → 3 times per month

The most tawdry thing about this scenario is thatFailover mechanismWhen a node is blocked, the scheduling system switches the alternate line within 50ms, and the business side is completely unaware.

Maintenance tips that even a novice can understand

Proxy services are not bought and finished, there is something to be said for routine maintenance:
1. Weekly checksIP Reputation Score(ipipgo backstage available)
2. Monthly updatesClient Certificates(Remember to turn on automatic updates)
3. QuarterlyLink quality testing(Speed measuring tool in the background)

Don't panic when you encounter a sudden ban, turn it on at the console immediately!Emergency protection mode. This mode will enable the cold protocol + random jitter algorithm to help you re-establish a secure connection in less than 5 minutes.
