Login State Crawler Practice: Cookie Pool Maintenance and Session Reuse

Why are logged-in crawlers always blocked? Look for your own problems first

Anyone who has ever worked on a crawler understands that login state maintenance is a bottomless pit. Yesterday was a good cookie, today suddenly invalid; just built a good session pool, half an hour was marked by the site wind control. At this time, don't be in a hurry to scold the platform, first look at whether you are using the local IP in the crazy request ---The same IP high-frequency operation, like shouting "I am a crawler" with a loud speaker, if you do not block you block who?

Cookie pools are not safes, they have to be used with proxy IPs.

Many newbies think that if they get a cookie pool, everything will be fine, only to find that the survival time is not as good as a goldfish memory. The real secret lies in:Each cookie must be bound to a separate IPThe first thing you need to do is to get a good deal of money. To give a chestnut, you log in from Shandong account suddenly cut to Hainan IP, the platform does not wind control only strange. At this time it is necessary to use ipipgo proxy service, to each cookie allocationFixed geography + long term survivalThe IP.

Session reuse has a way of working, IP stickiness is important

Some websites not only want cookies, but also session continuity. At this time, just change the IP will be bad - imagine you are in the bank transfer, suddenly the IP becomes a foreign node, the system does not freeze the account is strange. The solution is to use ipipgo'sIP Fixed PackageThe key session is bound to a specific IP, with a heartbeat mechanism to keep it online.

Hands-on skills:
1. For important accountsexclusive IPIf you want to use a dynamic pool for your regular account, you have to use a dynamic pool for your regular account.
2. Automatic access to the Personal Center every 30 minutes to preserve life
3. Immediately switch to the same geographical IP when encountering the verification code

Guide to avoiding pitfalls: blood and tears experience in the real world

Case 1:An e-commerce platform suddenly blocked at 3:00 a.m.
The problem is: all crawlers use the IP of the Jiangsu server room, which triggers the geographical aggregation detection.
Solution: switch to ipipgo'sReal User Distribution ModelDistribution of IP in proportion to the population of the province

Case 2:Crawling data works fine, but order placement fails
Root cause: the IP of the payment session must be the same as the login IP
Processing solution: real-time access via ipipgo's APIInitial Login IPFor critical operations

Frequently Asked Questions QA

Q: How long do cookies last on average?
A: 2-3 hours under normal environment, with ipipgo fixed IP can maintain more than 12 hours

Q: What should I do if I encounter slider validation?
A: Immediately stop the current IP and replace it by ipipgo4G mobile IP in the same provinceretry

Q: How much IP volume is needed to be sufficient?
A: Formula calculation:
Number of IPs = Number of Accounts × (24 / Hours of Daily Use per Account)
A chestnut: 100 accounts each with 6 hours a day, need 400 IP. recommended directly on ipipgo's dynamic pool, on-demand allocation is not wasted!

Time to gear up.

At the end of the day, a login state crawler is aIP Management Game. Instead of picking up garbage in free proxies, use ipipgo's commercial solutions. There are a couple of particular top points in their house:
- Coverage of 334 prefecture-level cities across the country, want to Tieling IP have
- Automatically cleans up flagged IPs more than you care to do yourself
- Supports IP binding by session granularity, no need to write your own scheduling logic

A certain sound project that I've been working on recently, using theirEnterprise-class dynamic pools, 3000+ accounts have been running steadily for two months. Remember the core principles:Make each account's IP behavior look like a real personThat's the key to a long-lasting war.
