Short-acting http: Short-acting HTTP proxy application scenario analysis

What the hell does this thing do? The Short HTTP Proxy Playbook

Anyone who has ever been in the internet knows that having your IP blocked is as bad as stepping on dog shit. The short-lived HTTP proxy thing is like aA Sichuan opera singer who can change facesThe new face is always new to you. Today, let's break it down and talk about the occasions when this stuff will make you scream.

I. The three best things about short-acting agents

1. second change of armor: Automatic IP change every 5-30 minutes, faster than a Sichuan opera face change
2. invisibility cloak: Disguised with a real residential IP, the site can't tell if it's a person or a machine!
3. use up or throw away: IP auto-destruction at the end of a single mission without leaving a trace

To give a chestnut, do e-commerce price monitoring Zhang San, with ipipgo's dynamic residential agent, every hour automatically change IP to catch the data. The website wind control system to see all the real people browsing records, sealing IP?

import requests

 Example of an API call to ipipgo
proxy = {
    'http': 'http://user:pass@gateway.ipipgo.com:9020', 'https': 'http://user:pass@gateway.ipipgo.com:9020'
    'https': 'http://user:pass@gateway.ipipgo.com:9020'
}

resp = requests.get('target site', proxies=proxy, timeout=10)

Second, these lines can't be separated from it

1. A must for e-commerce veterans
- Price monitoring should be diligent, but website counter-crawling is not vegetarian
- With dynamic IP polling collection, daily average of 100,000 + data easy to take!

2. Social media operations
- Raising a number is like raising a fish. Frequent operation is bound to kill you.
- Independent IP for each account, randomized operation interval

3. Ticket and coupon grabbers
- Scalpers know how to do it. Multiple IP concurrency.
- Be careful to control the frequency of requests, don't crash the server!

III. Guide to avoiding the pit (blood and tears version)

1. The protocol has to be right.: Don't use Socks5 for HTTP sites, it's like going off-road in a sedan!
2. Timeout should be set.: 8-15 seconds recommended, too long to delay efficiency
3. The IP pool has to be big enough: Prepare an IP reserve of at least 10 times the concurrency.

Recommended for ipipgoDynamic Residential (Enterprise Edition)The company's TK dedicated line has a latency of less than 200ms, which is faster than a mouthful of water. Their TK line measured latency less than 200ms, faster than the effort of drinking water.

Fourth, QA time (white must see)

Q: Will short-acting agents be slow?
A: It depends on the quality of the provider. Like ipipgo's cross-border line, the measured download speed can be up to 3MB/s, brush the video are not stuck!

Q: How often is it appropriate to change IPs?
A: Ordinary collection is changed in 30 minutes, and robbing type of business is recommended to be changed in every request.

Q: How do I prevent account linkage?
A: Remember this formula: 1 account = 1 IP + independent browser environment

V. The doorway to selecting a service provider

Don't just look at the cheap price, keep an eye on these three indicators:
- IP Survival Rate (direct pass below 90%)
- Customer service response time (don't consider anything over 2 hours)
- Is there a fail-over mechanism?

Like ipipgo supportAuto reconnect + IP cut in seconds, add an exception catch in the code and you're good to go. Their static residential IPs are $35/each/month for scenarios that require long term fixed IPs.

Finally, to say a big truth: proxy IP used well, can make you double the efficiency of the work. But don't use it to do illegal things, always walk by the river where there are not wet shoes, you know.
