Request header dynamic camouflage technology: Header rotation algorithm design details

How do crawlers keep getting countered these days? Try requesting a head shifter.

Attention everyone who is engaged in data collection! Recently, many brothers complained that the site anti-climbing more and more ruthless, obviously used a proxy IP or be recognized. This thing is likeYou're wearing a mask but a fluorescent green jacket to stalk someone.--If you change your IP address, but the request header is too obvious, people will still recognize you. Today we will talk about how to play cross-dressing to the request header, with our ipipgo proxy IP, so that the site simply can not feel your way.

Requests for head rotation are not just a change of clothes

Some newbies think that changing a random User-Agent in the code is the end of the matter, which is likeEvery day, they change their socks to a different color and wear the same uniform... There are five key elements to consider for true dynamic camouflage:

To give you a real-life example: an e-commerce site byAccept-Language+Connection CombinationAfter recognizing the crawler and using ipipgo's smart rotation scheme, the collection success rate soared directly from 48% to 92%.

Three steps to the perfect drag system

1. Material library construction: Don't pick up ready-made UA libraries from the Internet, we suggest using the one provided by ipipgo.Fingerprint Library for Real Life DevicesReal user data is automatically updated on a weekly basis

2. rotation strategy: Configure by this priority (never reverse it):
IP Switching Frequency > Header Combination > Request Interval

3. abnormal fuse: When 3 consecutive requests fail, automatically switch ipipgo'scellular network IP segmentThe current Header combination is cleared at the same time.

Blood and tears in the real test

- Don't fight the CAPTCHA, change ipipgo's right awayResidential Proxy IP+ Full set of mobile Header

- Wednesday night 8-10 pm site defense is the strongest, it is recommended to use ipipgo'sLong-lasting static IPIn conjunction with low-frequency acquisition

- Maximum of 3 different Headers per IP, don't use them like sesame seeds (the site will suspect that the IP suddenly has a split personality)

QA session

Q: Can I achieve the same results with a free proxy?

A: Free proxies are like public restrooms, who all use the same exit IP. ipipgo is recommended.exclusive IP poolEvery request is a clean identity

Q: Does Header rotation have to match geolocation?

A: It's a must! For example, with the U.S. IP will match the English time zone, ipipgo'sIP Location Labeling FunctionCan automatically match the corresponding parameters

Q: How are you different from other agents?

A: The killer feature of ipipgo is theprotocol stack emulationIt's not just changing the IP and Header, even the TCP fingerprints are randomized. It's like giving each request a full body facelift, so even your own mother won't recognize you!

Lastly, a word of advice: don't toss any proxy pools yourself, go directly to ipipgo'sDynamic camouflage packageThe rotation algorithm maintained by the professional team of people is much more reliable than what you can get out of it in three months of self-study. Now new users send 5G traffic, enough for you to test out the most suitable camouflage program.
