Reverse Anonymous Proxy: A Guide to Building a Reverse Anonymous Proxy Server for Website Stress Testing

What is a reverse anonymous proxy? Why is it needed for website stress testing?

Have done the website stress test understand, a single simulation of a large number of requests is easy to be recognized by the target server. It's like registering 100 accounts with the same cell phone number, the system will pull the plug on you in minutes. This is the time toReverse anonymous proxyTo act as a "stand-in" - spreading the test requests to different IP addresses, masquerading as real user access.

Here's a pitfall to be aware of: ordinary proxy IPs tend to expose test behavior. For example, some proxy servers will modify the request header, or leave special marks in the traffic. At this timeipipgoResidential proxies at home come in handy, as they provide real home network IPs with request characteristics that are identical to those of ordinary Internet users, so that even the operators can't tell the difference.

Hands-on with reverse proxy servers

Don't be in a hurry to get started, let's get the tools ready first:
1. Linux-capable servers (1 core 1G is sufficient)
2. ipipgoAccount number (remember to select dynamic residential IP)
3. Nginx (just don't make it too old)

The configuration process is a three-step process:

Avoiding three common potholes

Pit 1: High IP duplication rate
Suddenly in the middle of the test, I found a lot of requests for the same IP? Eighty percent is using a static proxy. Replace it withipipgoThe dynamic residential IP, set to switch automatically every 5 minutes, immediately solved.

Pit 2: HTTPS request failure
This is most likely a certificate configuration issue. Turn on the ssl_preread parameter in Nginx, and don't change the order of the certificate chain.

坑三：忽高忽低
It is recommended that theipipgo后台筛选低地区，别图省事选全球模式。测试美国网站就锁定美西节点，速度能稳定在200ms以内。

Practical Lightning Avoidance Q&A

Q: How many IPs are enough for stress testing?
A: Don't be fooled into buying a large number of IP! Ordinary website testing 200-500 dynamic IP is enough, the key to look at the concurrency control. UseipipgoThe intelligent rotation function of 50 IPs can also simulate thousands of users.

Q: Why is there a big gap between test results and real users?
A: Check whether the User-Agent in the request header has been randomized or not, it is recommended to use the real browser fingerprint library. Also note thatipipgoThe time zone setting should match the target user's region.

Q: What should I do if I encounter a back-crawling website?
A: First, see if the IP quality is not good. Using a residential proxy is much more reliable than a server room proxy, theipipgoThe residential IP of the home comes with a real home network environment that is not prone to triggering wind control.

Hard criteria for choosing a proxy service provider

One last tip for picking a proxy service provider:
1. Look at the type of IP - residential IPs are more resistant to blocking than server room IPs.
2. Look at the protocol support - socks5/http(s) must be fully supported!
3. Look at geographical coverage -ipipgoThis covers 240+ countries, so you won't lose your head in measuring cross-border operations.
4. Look at the level of anonymity - high stash proxies do not expose proxy information in the request header

According to this criterion to choose, guaranteed that your stress test data is real and reliable. Remember not to use free proxies for cheap, when the test data is not allowed, the server is also blocked IP, can not cry.
