When Crawlers Meet CAPTCHA? Try this hidden trick
A while ago to help friends debug data collection script, found a strange phenomenon: obviously with a common proxy IP, the target site or frequent pop-up verification code. Later, the proxy was switched to tunnel mode, and the collection speed was directly doubled without triggering the wind control. What is the hidden doorway here?
Traditional proxies are like single-line liaisons, where the connection has to be re-established for each request. Tunnel proxy is equivalent to give you with an exclusive courier, the client and the server always maintain an encrypted channel. To give a practical example, when collecting an e-commerce platform with an ordinary agent, every 5 requests will have to change IP, while the tunnel agent sends 50 requests in a row will not be recognized.
Python Example - Tunnel Proxy Configuration
import requests
proxy_host = "tunnel.ipipgo.com:9021"
proxies = {
'https': f'socks5://{proxy_host}'
}
response = requests.get('destination URL', proxies=proxies, timeout=30)
Three Minute Getting Started Configuration Guide
Don't be intimidated by the jargon, configuring a tunnel proxy is easier than ordering takeout. Take the popular Chrome browser as an example:
1. Open Settings → Advanced → System → Open Proxy Settings
2. Check the "Use proxy server" box in the Connections tab.
3. Address fieldgateway.ipipgo.netPort Fill9018
4. Remember to check "Use the same proxy for all protocols".
If you are doing automation scripting, we recommend using the SDK toolkit provided by ipipgo. Their API interface is designed to be very user-friendly, and the docking code is no more than 10 lines. Tested an e-commerce platform commodity data collection, the average daily processing volume from 30,000 to 200,000, the probability of IP blocked down 80%.
These scenarios must use a tunneling agent
| Business Type | General Agent | Tunnel Agent |
|---|---|---|
| Short video data collection | 3-5 disconnections per hour | Stable operation for 12 hours + |
| Social platforms to raise numbers | Frequent requests for secondary validation | Stay logged in for 7 days |
| Price comparison software monitoring | Data delayed by 15 minutes | Real-time price updates |
In particular, if you need to maintain long connection scenarios, such as live data monitoring or online games, the TCP long connection feature of the tunnel proxy is simply tailor-made. There is a cross-border e-commerce friends, with static residential packages to do store management, the same IP continuous login half a year have no problem.
Handbook on Mine Clearance of Common Problems
Q: Will tunnel reps be more expensive?
A: ipipgo dynamic residential package, for example, the tunnel mode per GB of traffic costs 20 cents more expensive than the ordinary mode, but the savings in IP replacement time and retry costs, the actual overall cost instead of reducing 40%
Q: Authentication failure when connecting?
A: Ninety percent is that the whitelist is not set properly. Remember to add the local server IP to the authorization list in the ipipgo console, and remember to open a cross-border line for overseas business.
Q: How can I tell if I should use static or dynamic?
A: Remember the mnemonic:
- Registered to raise the number to choose static (35 yuan / month / IP)
- Dynamics for data collection (from $7.67/GB)
- Dedicated TK line for transnational operations
Hidden Tips for Choosing Packages
Seen too many people blindly choose the most expensive package, in fact, completely unnecessary. Share a real case: a financial company started directly on the enterprise version of the package ($ 9.47 / GB), and then we helped them do a traffic analysis, found that 80% request in fact, with the standard version ($ 7.67 / GB) can be dealt with, saving more than 60,000 budget per year.
ipipgo has a particularly useful traffic monitoring feature that can be seen in real time in the background:
- Traffic consumption by protocol type
- Peak hour distribution
- Volume of geolocation requests
Adjusting package combinations based on these figures can often save 30%-50%.
Lastly, newbies are reminded to pay attention to the following: use the pay-per-volume model during the testing phase, and then switch to the monthly package after the official launch. If you encounter a sudden surge in concurrency, remember to contact customer service to temporarily open a traffic refueling package to avoid business interruption.
