Proxy IP Request Header Randomization Technology | Simulates Real Browser Fingerprints

Recognized as a crawler by a website? It may be that your 'digital ID' is exposed

Many users are still blocked when they are collecting public data, even though they have changed the proxy IP. This situation is often not a problem with the IP itself, but with yourrequest header informationrespond in singingBrowser FingerprintingRevealed. Just like a real-life ID card, each web request comes with its own digital signature, and poor handling of these details can trigger website protection mechanisms.

The devil's details in the request header

Every HTTP request contains User-Agent, Accept-Language and other parameters. The fixed and unchanging request header is like holding up the "I'm a robot" sign, as we found in our real-world testing:

When using the ipipgo proxy service, it is recommended to work with theirRequest Header Dynamic Generation InterfaceIt can automatically match the common device parameters of the region where the current proxy IP is located. For example, when switching Japanese IP, it will automatically generate the request header combination corresponding to the Japanese environment.

Your mouse track is betraying you.

Modern websites recognize browser fingerprints with 200+ parameters, including:

• Screen resolution fluctuation range (real people will have ±3 pixel error)
• Match between time zone and IP location
• Font list sorting method
• Canvas image rendering features

We have tested an e-commerce platform: using the same proxy IP, the access survival time of fixed fingerprints is no more than 5 minutes, while dynamic fingerprints can be maintained for more than 2 hours.

Build a Real Digital Identity in Three Steps

1. environmental isolation: Create a separate browser instance for each proxy IP, recommended to use the headless browser's MultiProfile feature.
2. parameter confusion: The following parameters are randomly adjusted per request:
　- Insertion of non-useful compression formats in Accept-Encoding
　- Disrupting the order of HTTP header fields
　- Add harmless random request headers (e.g. Sec-CH-UA-Platform-Version)
3. Behavioral simulation: Insert random intervals between key actions (0.5-3 seconds recommended) and design non-linear mouse movement trajectories

QA: Practical Frequently Asked Questions

Q: How do I verify that my fingerprints are valid?
A: VisitsBrowser Fingerprinting Test Page, focusing on checking whether WebGL fingerprints, AudioContext hashes are different every time

Q: Why is a residential agent better than an engine room agent?
A: The TCP stack characteristics of the server room IP are obvious, for example, the initial TTL value, window scaling factor and other underlying parameters are easily recognized. ipipgo's residential agent is from a real home broadband, and the TCP fingerprints are exactly the same as those of normal users

Q: Do I need to maintain my own fingerprint database?
A: It is recommended to use ipipgo'sFingerprint Hosting ServicesTheir dynamic fingerprinting engine updates a library of 5,000+ device signatures every hour, automatically matching popular device models in the region where the proxy IP is located.

Technology isn't everything.

Finally, we would like to remind you that there are limitations in any technical means. Our team's actual test data shows that the average survival cycle of relying solely on proxy IP is 4.2 hours, while the effective cycle can be extended to 28 hours after combining request header randomization and dynamic fingerprinting. However, the specific effect also depends on the strength of the wind control of the target website. It is recommended to first use ipipgo'spay-per-use modelPerform small-scale testing.
