Reverse proxy application scenarios: reverse proxy use case analysis

What can a reverse proxy really do? Teach you how to use proxy IP to solve real problems.

Folks may have heard of the word reverse proxy, but the specific how to use the proxy IP to operate estimates a little confused. Let's take a few grounded scenarios today, break open the rubbing said clearly.

Scenario 1: Website can't carry the traffic? Try dynamic IP diversion

Last year, there was a customer who was a hip brand e-commerce company, and the website was directly overwhelmed by the traffic. Later, they used our ipipgo's Dynamic Residential (Standard) package with reverse proxy on Nginx to spread the traffic to 10 servers. Here's the kicker:Each server uses a different proxy IP to connect to the databaseThis prevents blocking and maintains stability.

 Nginx Configuration Snippet Example
upstream backend {
    server 192.168.1.10 max_fails=3; bind proxy IP1
    server 192.168.1.11 max_fails=3; bind proxy IP2
    upstream backend { server 192.168.1.11 max_fails=3; bind proxy IP2
}

server {
    keepalive 32; } server { listen 80; }
    location / {
        proxy_pass http://backend; proxy_set_header
        proxy_set_header Host $host.
    }
}

This trick is especially suitable for e-commerce platforms with traffic peak planting hours, using dynamic IP pool rotation to share the pressure. Our dynamic residential package price of $7.67/GB is more than half cheaper than self-built servers.

Scenario 2: Anti-Crawler? Reverse Proxy as a Shield

There is a client who does knowledge payment, the courseware is always moved by crawlers. Later on, the reverse proxy layer was added withIP access frequency limitation, combined with ipipgo's static residential IP to do whitelisting. Get it exactly this way:

1. Counting IP requests with Lua scripts
2. Automatically cut to alternate IP if threshold is exceeded
3. Static IP bindings for core interfaces and dynamic IPs for general requests.

So tossed, the crawler recognition rate dropped 80%. the point is to use a static IP to protect the core business, and a dynamic IP as a buffer layer.

Scenario 3: Cross-country access to the card into a dog? Dedicated proxy to accelerate

Do cross-border e-commerce know, overseas users visit the domestic server that is a slow. We have a customer with a TK line as a reverse proxy, the static resources cached to overseas nodes. Let's take a chestnut:

The key is to put the database in the country and use proxy nodes for caching on the front end. Users access the nearest proxy node and the speed takes off straight away.

Scenario 4: Data collection always blocked? Dynamic IP pool rotation

There is a customer who does public opinion monitoring and grabs millions of data every day. Previously, the single IP was always blocked, and then it was realized by using our Dynamic Residential (Enterprise Edition) package with reverse proxy:

1. Automatically change proxy IP every 5 minutes
2. Different IP segments for different lines of business
3. Automatic switching of alternate channels for failed requests

The success rate dried right up from 47% to 92%, with the focus being toSetting a reasonable switching frequencyDon't change it too hard to be recognized as an anomaly.

QA Frequently Asked Questions

Q: What is the difference between a reverse proxy and a normal proxy IP?
A: Reverse proxy is used by the server, like a mask for the server; ordinary proxy is used by the client, like a vest for the user

Q: Do I choose a dynamic or static package?
A: Frequent change of IP selection dynamic (such as data collection), fixed business with static (such as API docking)

Q: What should I do if my IP is blocked by mistake?
A: Contact ipipgo customer service to take the whitelist channel, unblocked within 1 hour

Recommended ipipgo packages

It's more cost-effective to choose a package based on your business needs:

Need to customize the program directly to technical customer service, we support 1v1 configuration program. In particular, cross-border business, with TK dedicated line can save 30% more than the delay cost.

Finally, a nagging word: reverse proxy is not a silver bullet, you have to combine the characteristics of the business to configure. It is recommended to test the dynamic package first, and then switch to the static package after stabilization.
