https relay proxy: HTTPS relay proxy building tutorial, secure encrypted transmission

Hands-on with a secure delivery station.

Anyone who has worked on a web project knows thatHTTPS transit proxies are like crypto couriers, pack the data into a password box for transmission. For example, you want to send important documents from Beijing to Shanghai, ordinary courier may be unpacked to see. But with our ipipgo encrypted courier service, the entire password box transportation, to the destination before using a special key to open.

The most tangible use for this stuff is:Anti-snooping, anti-tampering, anti-dropoutThe following are some of the reasons why you should use a proxy. Especially for those who do data collection, using a normal HTTP proxy is like running around naked, the website can always recognize that you are using a proxy. After the HTTPS relay, the transmission content can not even be understood by the operator.

Don't be blind to the preparation tools.

Let's mess with the least expensive option:

Must have three sets:
1. server (Ali cloud / Tencent cloud can be)
2. domain name (buy a cheapest .top)
3. SSL certificate (Let's Encrypt free application)

Focus on server siting:Don't crowd the popular server rooms.The first thing you need to do is to try the Netherlands or Frankfurt nodes. Like doing business in Europe and the United States, do not pile up the Silicon Valley server room, try the Netherlands or Frankfurt nodes. Our ipipgo cross-border special line agent is specialized in solving this kind of problem, the global 200 + nodes to pick.

Don't step on the pitfalls of real-world configuration

Using Nginx as an example, see here for the key configuration:

server {
    listen 443 ssl; server_name your domain name; listen 443 ssl; listen 443 ssl
    server_name your domain name.

    ssl_certificate /path/to/fullchain.pem; ssl_certificate_key /path/to/privkey.pem
    ssl_certificate_key /path/to/privkey.pem;

    location / {
        proxy_pass http://代理服务器IP:端口; proxy_set_header Host 1
        proxy_set_header Host $host; proxy_set_header X-Responsor; proxy_set_header X-Responsor
        proxy_set_header X-Real-IP $remote_addr; }
    }
}

Three points where it's easy to roll over:

1. Certificate path is written incorrectly (absolute path is recommended)
2. Forgetting to open fire ports (443 and 80 must be open)
3. No header forwarding set (resulting in anomalies in target site recognition)

Choosing the right agent is reliable

Building your own transit server is a technical job, but if you don't like the hassle, it's easier to just use an off-the-shelf one. Like our ipipgoStatic Home PackageIt's 35 bucks a month and comes with tech support:

Those of you who have used it know thatTK LineEspecially friendly to cross-border e-commerce, much more stable than self-built transit. Last time there is a do independent station buddy, with our program after the API call success rate from 67% directly pull to 98%.

Guidelines on demining of common problems

Q: Why is access slowed down after configuration?
A: Check three points: 1. server geographic location 2. proxy IP type (recommended to change the static residential) 3. whether the certificate has expired

Q: What should I do if I get a 502 error?
A: Eighty percent of the back-end agent hangs, first with curl test proxy server connectivity. If the self-built is not stable, it is recommended to change ipipgo's enterprise-class dynamic proxy.

Q: How can I prevent my IP from being blocked?
A: The key to good request frequency control, with ipipgo's dynamic rotation package, set a reasonable switching interval. Never use the data center IP hard just, minutes into the blacklist.

Engage in technology is afraid of closed doors, encounter specific problems can be directly find ipipgo technology brother. They support 1 to 1 program customization, the last time a crawler team, with dynamic + static mixed program, the cost of saving four not to mention the collection efficiency has doubled.
