Reverse Proxy Role: Analysis of Reverse Proxy Application Scenarios

What is a reverse proxy? Let's find out what it can do.

Speaking of reverse agency, many old iron will be associated with the "middleman", but it can be much more real than the middleman. To give a grounded example: there is a janitor in front of your neighborhood, all the couriers are first sent to the grandfather there, the grandfather and then distributed to all households - the grandfather is a reverse agent. Things to do includeHelp servers carry traffic, hide real IPs, and filter dangerous requests., especially suitable for business scenarios that need to handle a large number of visits.

Real life examples show you: reverse proxy can do what big things

1. E-commerce spike to carry the pressure of the magic weapon: Last year's double eleven a platform with reverse proxy cluster diversion, hard to press the server crash rate to 0.3% below. With ipipgo's static residential IP as the entry node, effectively dispersing the instantaneous traffic of 60%.

2. Must-have anti-creeper tips: A ticket site used reverse proxy + dynamic IP rotation to identify 120,000 malicious crawls. Here's an example configuration:

location /api {
    proxy_pass http://ipipgo_动态IP池;
    proxy_set_header X-Real-IP $remote_addr;
}

3. Cross-border business gas pedal: Reverse proxy with cross-border dedicated IP, a cross-border e-commerce loading speed from 8 seconds down to 1.2 seconds. Here pay attention to choose to support Socks5 protocol services, like ipipgo TK line is particularly suitable for this scenario.

Three gateways to choosing a proxy IP Don't step in the pits!

Look at the protocol match:

Be smart about counting costs:Dynamic IP is suitable for high-frequency switching scenarios, such as ipipgo's dynamic residential package, which is enough to run tens of thousands of requests with more than 7 dollars of 1G traffic. Static IP is more suitable for businesses that require a fixed identity, such as long-term login account management.

There's a trick to measuring quality:I'll teach you a dirt method - send 10 consecutive requests to https://ip.ipipgo.com/check and see if the returned IP locale and carrier are stable. Remember to automate the test with code:

import requests
for _ in range(10): res = requests.get('', proxies={'https': 'ipipgo proxy' })
    res = requests.get('https://api.ipipgo.com/check', proxies={'https': 'ipipgo proxy address'})
    print(res.text)

Q: What is the difference between a reverse proxy and a forward proxy?
A: To give a chestnut: the forward agent is that you find a surrogate to help you buy things, and the reverse agent is that the supermarket itself has set up a unified cash register at the door. The former helps you hide, the latter helps the server carry things.

Q: What should I do if I often timeout when testing proxy IP?
A: 80% of the protocol is not paired, like the need to maintain a long connection scenario, remember to add a timeout retry mechanism in the code:

requests.get(url, proxies=proxies, timeout=(3, 7))

Q: What's the best way to get the best deal on ipipgo's packages?
A: data collection choose dynamic standard version, account raising with static residential, need high concurrency choose enterprise version. Their technical customer service can help do the stress test, than their own blind try to save time.

To be honest, why do you recommend ipipgo?

Experience after using it for over two years says that this oneCross-border special lines are indeed stableI'm not sure if I can do it. Last time to help customers do cross-border data synchronization, with ordinary proxy 10 minutes to break once, replaced with their TK line for 48 hours without dropping. Focus on complimenting the API design, much more concise than others, take the IP on two lines of code:

import ipipgo
client = ipipgo.Client(api_key="your key")
ip_list = client.get_proxies(count=50)

In terms of package price, the Enterprise Edition is more than $2 more expensive than the Standard Edition, but the extraDedicated Link Guaranteeand failover automatically. If it is a long-term project, it is recommended to directly find their customer service to ask for a 1v1 program, which can adjust the billing method according to the business fluctuations, and is more cost-effective than sticking to the fixed package.

A final note to newbies: don't just look at the number of IPs thatQuality is king.The first is to buy a garbage IP for cheap. A customer to buy cheap garbage IP, the results of the account was blocked all, the loss than the proxy fee dozens of times more. Now honestly use ipipgo static residence, registration through rate from 23% soared to 89%, this money is worth spending!
