What the heck is HTTP/2 fingerprinting?
We usually use proxy IP to surf the Internet, the server will actually secretly check your network fingerprints. Just as you go to the bank to do business with the fingerprint, HTTP / 2 protocol also has its own "fingerprint characteristics". Now many websites have upgraded detection methods, just change the IP address may not be enough, you have to change the fingerprint characteristics of the protocol layer with the real browser exactly the same.
As an example, there are some websites that will stare at yourALPN Expansion SequenceNot put. Ordinary proxy software may use a default ordering like h2,http/1.1, but Chrome actually has http/1.1 in front. If you don't pay attention to this kind of detail, you will be recognized even if you use more proxy IPs.
Teach you how to adjust fingerprint parameters
Here are a few practical tips for the guys:
① Disguise client identifier
Open your agent software configuration file and find the paragraph h2_settings. Focus on changing these parameters:
| HEADER_TABLE_SIZE | Suggestion to change to 65536 |
| MAX_FRAME_SIZE | Set it to 16384. |
| INITIAL_WINDOW_SIZE | Fill in 6291456. It's the best bet. |
② Simulating Browser Behavior
Remember to putFlow CharacteristicsTune it naturally. For example, if you use ipipgo's residential proxy to do testing, you can switch IPs in different areas at different times, so don't always focus on the same city. Their dynamic IP pool has 50 million+ resources, so you can just cut and use them without fear of duplication.
Recommended Debugging Tools
Don't just use browser developer tools to see the parameters, here are two recommended tools:
- h2spec - Specialized detection of HTTP/2 protocol compliance
- ja3transport - Clients capable of generating specific fingerprints
Use ipipgo's proxy IP with these tools to connect to their service before debugging. They support minute-by-minute billing, so it doesn't hurt to use it during the debugging phase.
Frequently Asked Questions QA
Q: What should I do if I am still recognized after adjusting the parameters?
A: 80% is that the TLS fingerprints are not processed cleanly. Suggest using ipipgo'sAdvanced Encryption Protocolservice, their TLS parameters by default just mimic the latest version of Chrome.
Q: How do I test the fingerprint camouflage effect?
A: Go to a fingerprinting site (such as tls.peet.ws) and test it more than three times. Remember to change ipipgo's different nodes each time, focusing on the detection results of both HTTP/2 and TLS.
Why do you recommend ipipgo?
Their home technology team has specialized in protocol layer optimization and three hardcore advantages:
1. SupportCustom protocol stacksThe h2 parameter can be adjusted as needed.
2. Each IP has a real device fingerprint, not generated by a virtual machine.
3. 47 backbone nodes around the world with low latency during commissioning
The last thing I want to say is that tuning fingerprint parameters is a delicate job. Just like the car to do tuning, the engine (proxy IP) to be strong enough, the transmission (protocol configuration) must also be tuned in place. ipipgo this brand I have used for half a year, the protocol camouflage this is really more reliable than others, encountered technical problems to find their customer service response is also fast, suitable for the need for fine operation of the old drivers.
