Use Rotating Proxy in Scraping Scripts

We release new services rotating open proxy (unstable public proxies) and rotating premium proxy (stable premium proxies) recently. They aim to make it easier for scripts to switch IP while doing scrape tasks.

Regular Proxy

When using regular proxies, your scripts need to do these things in order to use different IPs to scrape the web pages.

• Get a proxy list from your proxy provider by API (example).
• Use a proxy from the list to scrape web pages.
• Change to another proxy to avoid that IP being blocked.
• After a while (one hour), get a new proxy list (Step 1).

Rotating Proxy

When using our rotating proxy service, your script needs only one proxy to do the jobs. It doesn’t need to download a proxy list and change proxies. We rotate the IPs for you.

Use the Proxy

Our rotating proxy supports both HTTP(S) and Socks5. If you use IP authentication, no username/password is required.

Sample Scripts

Here are some sample scripts showing how to use our rotating proxy as an HTTP(S) proxy with username/password authentication.

In the code, we use gate.proxy.com as the demo proxy host. You should use the real proxy host or IP in your script.

We use the URL http://checkip.amazonaws.com for the test. It returns its visitor’s IP. You should see a new IP every time you use our rotating proxy to access it.
