HTTP/HTTPS dual-protocol proxy server construction guide

I. Why do you need dual protocol support?

Nowadays, websites are likehybrid carFor example, if you are crawling an e-commerce site, the product details page may be HTTP, but the user review interface requires HTTPS. For example, if you're crawling an e-commerce site, the product details page might be HTTP, but the user reviews interface requires HTTPS. with a single protocol proxy you'll run into two headaches: either the encrypted request fails, or the normal request is intercepted.

Recommended hereipipgo Dynamic Residential IPIt can be automatically switched to adapt its intelligent protocol recognition function. For example: when detecting that the target website is enabled with HTTPS, the system will automatically assign IPs that support SSL handshake, and the success rate is higher than that of ordinary proxies by more than 40%.

Second, the white can also handle the building process

Step 1: Prepare the ingredients
1. Rent a cloud server (2-core 4G to start, recommended Ubuntu system)
2. Open the ipipgo console and create the"Dual protocol dedicated IP pool"(Remember to check the "Auto Protocol Adaptation" option)
3. Install Nginx on the server, version 1.18 or higher is recommended.

Step 2: Configure the secret sauce
Modify the Nginx configuration file (/etc/nginx/nginx.conf):

 http { server { listen 8888.

     # HTTP processing channel
    location /http {
        proxy_pass http://$target_url; proxy_set_header X-Real-IP $ { ipipgo dynamic IP}
        proxy_set_header X-Real-IP ${ipipgo dynamic IP};
    }

    # HTTPS processing channel
    location /https {
        proxy_ssl_server_name on; proxy_pass ; }
        proxy_pass https://$target_url:443; proxy_set_header Host $host; proxy_set_header
        proxy_set_header Host $host.
    }
}

}

Save and executesudo nginx -s reloadtakes effect. The beauty of this configuration is that differentiating protocols with different paths saves resources over opening multiple ports.

Step 3: Bind IP resources
Go to the ipipgo developer center to get the API key and set up two key rules:
1. When the HTTPS request fails 3 times, automatically change the IP that supports TLS1.3
2. Automatically clean up IPs that have been used for more than 12 hours in the early hours of each day.

IV. Enterprise-level program expansion

If you are processing 100,000+ requests per day, it is recommended that you use thedistributed architecture::
1. Deployment of 1 server each in Tokyo, Singapore and Frankfurt
2. Adoption of ipipgoIntelligent Routing APIThe first one is for American users to automatically connect to the Silicon Valley node and Japanese users to the Tokyo node.
3. Cache high-frequency requests with Redis to reduce repeated crawling
A financial company used this method to increase the speed of data collection by three times.

v. guide to demining common problems

Q: How is building my own proxy better than using ipipgo's API directly?
A: There are three major advantages to building your own:
1. Caching strategies can be customized (e.g., images cached for 1 hour, text cached for 5 minutes)
2. Ability to do in-depth analysis in conjunction with internal monitoring systems
3. Lower cost over the long term (100,000 requests at 601 TP3T)

Q: Why do HTTPS requests sometimes break?
A: Check three places:
1. Nginx configuration with or without theproxy_ssl_server_name
2. whether the server time is accurate (time zone errors can cause SSL handshake failures)
3. whether ipipgo's IP pool is enabled or not"High encryption level screening"

Q: How do I test if the agent is working properly?
A: Detect with this combo:
1. Visit http://httpbin.org/ip to see if the returned IP has changed
2. Visit https://www.cloudflare.com/cdn-cgi/trace to check if HTTPS is working.
3. Viewed on the ipipgo consoleIP Usage ReportConfirm that the switching frequency is normal.

Q: Do I need to maintain the server?
A: Doing these three things every month is enough:
1. Update Nginx security patches
2. Clean up log files (prevent hard disk from filling up)
3. Refresh the IP binding relationship in the ipipgo backend

Follow this guide to build a stable and usable dual protocol proxy in as little as 1 hour. Now with ipipgo'sFree Trial PackageIt can experience the resource advantages of 90 million residential IPs, and all advanced features are open during the test period, especially suitable for enterprises that need large-scale data collection.
