Proxy IP anti-crawl warning circumvention: anti-crawl warning proxy circumvention strategy

What are anti-climbing warnings really protecting against? Let's get to the bottom of it.

The site to engage in anti-climbing like a supermarket anti-theft, the most annoying is the same face repeatedly appear. For example, if a treasure price monitoring script always use your home broadband IP, not block you block who? This time the proxy IP is yourface changerIf you change your "face" every time you visit, the site will not recognize that the same person is operating the site.

Choosing an IP is like buying clothes. Don't just look at the price.

There are three common types of agents on the market, and getting it wrong is a direct flip-flop:

Highlighting ipipgo's dynamic residential package, he has aReal Life Behavioral Simulationfeature that automatically adjusts the request interval, with a much lower probability of triggering backcrawl than ordinary proxies.

Practical battle to avoid the pit three axes

1. Don't be a fool and use sequential switchingMany newbies get the agent pool and use it in the order of ABCDE, which is no different from running around naked. The correct posture is to use a randomized algorithm to disrupt the order, like this:

import random
proxy_list = ['ip1:port','ip2:port','ip3:port']
random.shuffle(proxy_list)

2. The requesting head should be able to actRemember to use different User-Agents for different IPs, so that all requests don't have "Python-urllib" as a distinctive feature.

3. Be smart if you fail and retry.: encounter 429 error do not rush to change the IP, first hibernate for a random length of time (recommended 5-15 seconds), and then change the IP to retry, this is more in line with the operation of the real people!

Real Case: How to play e-commerce price monitoring

A client with ipipgo'sDynamic Residential (Enterprise Edition)Do a price comparison across the web with these parameters configured:

• No more than 3 consecutive requests from a single IP
• Automatic switching of browser fingerprints
• 300+ different ASNs (Autonomous System Numbers) used daily

As a result, the number of triggered anti-climbing times dropped from a daily average of 50 times to less than 3 times in 3 consecutive months, and the success rate of data acquisition was maintained at 98%+.

Tell the truth.

Don't believe in those $9.9 monthly proxy services, many of them are shared IP pools that have long been tagged rotten by the anti-crawling system. ipipgoDedicated Static IPAlthough the unit price is a bit higher, the measured blocking rate is only 1/7 of the shared IP. remember: in the anti-skimming attack and defense war, stable and reliable is ten times more important than cheap.
