With the rapid development and widespread adoption of the Internet, we have entered the era of big data. In today's work and life, everything is closely tied to data, making data collection and analysis paramount.

For many companies, web scraping is an essential process for data acquisition. However, websites often impose anti-web scraping measures, which may lead to IP blocking. To ensure safety, it is necessary to use proxies to perform these tasks.

But why do we need overseas HTTP proxies specifically?

Using HTTP proxies to enhance browsing speed: HTTP proxies can act as buffers to improve browsing speed. Proxy servers often employ large cache buffers to store website data.

When information passes through the proxy server, it saves relevant data. The next time you browse the same website or access the same information, the proxy can directly provide the saved data, significantly improving browsing speed.

Moreover, using proxies can help hide your real IP address and protect you from malicious attacks. Proxy Cloud's HTTP proxies can effectively address scraping speed and IP-related issues.

Using HTTP proxies to bypass IP restrictions: When a single IP is used too frequently, websites may impose limitations on access. To continue web scraping work, you need a large pool of stable IPs.

While there are numerous free HTTP proxies available online, they come with drawbacks. You may spend a lot of time searching for them, and even if you find a large batch of proxies, they may not be usable.

Now, let's examine the limitations of free overseas IP proxies:

Low IP connection success rate: Free HTTP proxies are often hosted on unstable servers with limited bandwidth, leading to frequent disconnections and an inability to maintain a stable online presence.

Lack of security guarantees: Free proxies are accessible to everyone, so you have no control over how others use them. This lack of privacy can be a significant drawback when you need to protect sensitive information or hide your identity.

Lower success rate for web scraping: With many users accessing free proxies, the success rate for web scraping can be significantly diminished. Using IP addresses that others have already used for the same purpose may result in a lower success rate.

High IP duplication rate: For enterprise-level web scraping, a vast quantity of effective proxy IPs is required. However, free proxies often have a low effective rate, typically ranging from 1% to 40%. Although they may offer large quantities of IPs, the actual number of usable IPs is quite limited due to duplicates and inefficiencies.

In conclusion, while free proxies may seem attractive, they come with significant drawbacks. Considering the limitations in IP connection success rates, security, web scraping success rates, and IP duplication, it is essential to be cautious when using free proxies. For more advanced features and to ensure a seamless web scraping experience, opting for paid overseas HTTP proxies is recommended.

How to Use Overseas HTTP Proxies?

Directly through browser or system settings: On your computer, open internet options, and under the LAN settings, select "Use a proxy server for your LAN." Enter the proxy IP address and corresponding port number before saving the settings to start using the HTTP proxy IP.

For mobile devices, find the proxy settings in the settings list, choose "Manual," enter the proxy IP address as the server hostname, input the port number, and save the settings.

After saving, searching "IP" on a search engine or using the "ipconfig" command on your computer will show that your IP address has changed.

Implementing network crawler code: For users seeking to gather a large amount of internet data in a short time through web scraping, HTTP proxies are indispensable. Network crawlers generally use code to programmatically interface with proxy APIs, allowing seamless switching of IP addresses during web scraping.

In conclusion, to ensure efficient web scraping, HTTP proxies are crucial. For a reliable and efficient solution, I highly recommend iproyal, an overseas HTTP proxy provider. Their IPs offer precise city-level geolocation, with the IP pool being updated monthly. As a trusted source for fast and stable data acquisition in the big data realm, iproyal provides a cost-effective and reliable service.
