Cool Proxy

There are HTTP proxy, FTP proxy, SOCKS proxy, SMTP proxy, CGI proxy. They differ only in the data transmission protocol used and the purpose for which they are used. For example, SMTP proxy allows you to organize a secure server for e-mail.

In data centers, proxies are used to provide IP to virtual servers. After all, one server there can be used by a dozen users at the same time. And each needs to be allocated its own IP and port. All this is done through proxies.

To speed up scraping by leveraging asynchronous programming in Python, you can use the asyncio library along with asynchronous HTTP requests. The aiohttp library is commonly used for asynchronous HTTP requests. Here's a basic example to help you get started:

Install Required Packages:

pip install aiohttp

Asynchronous Scraping Script:

import asyncio
import aiohttp

async def scrape_url(session, url):
    try:
        async with session.get(url) as response:
            if response.status == 200:
                content = await response.text()
                # Process the content as needed
                print(f"Scraped {url}: {len(content)} characters")
            else:
                print(f"Failed to scrape {url}. Status code: {response.status}")
    except Exception as e:
        print(f"Error scraping {url}: {str(e)}")

async def main():
    urls_to_scrape = [
        'https://example.com/page1',
        'https://example.com/page2',
        # Add more URLs as needed
    ]

    async with aiohttp.ClientSession() as session:
        tasks = [scrape_url(session, url) for url in urls_to_scrape]
        await asyncio.gather(*tasks)

if __name__ == "__main__":
    asyncio.run(main())

• • This script defines an asynchronous function scrape_url to perform the scraping for a given URL.
  • The main function creates an asynchronous HTTP session using aiohttp.ClientSession and gathers the scraping tasks.
  • The asyncio.run(main()) line runs the main asynchronous function.

• Running the Script:

python your_scraper_script.py

This example demonstrates the basics of asynchronous scraping. Asynchronous programming can significantly speed up scraping tasks, especially when making multiple concurrent HTTP requests.

Keep in mind that not all websites support asynchronous scraping, and some may have restrictions or rate limiting. Always adhere to the website's terms of service, and consider adding delays between requests to avoid overloading the server.

To know the host of a proxy server, you can follow these steps:

Check the proxy settings: If you are using a proxy on your device or within an application, examine the proxy settings to see if the host (IP address or hostname) of the proxy server is mentioned.

Observe the proxy URL: The proxy URL can sometimes indicate the host of the proxy server. For example, an HTTP proxy URL usually starts with "http://" or "https://" followed by the proxy server's IP address or hostname, while a SOCKS proxy URL typically starts with "socks://" followed by the proxy server's IP address or hostname.

Consult the proxy provider: If you are unsure about the host of the proxy server you are using, you can always consult the proxy provider or the documentation that came with the proxy server. They should be able to provide you with the necessary information about the proxy server's host.

Use online tools or software: There are various online tools and software applications that can help you identify the host of a proxy. By connecting to the proxy server and analyzing the traffic, these tools can often determine the host of the proxy server.

When using a proxy, Google Chrome warns the user about it at startup. To connect directly, you must disable proxies at system level. That is, go to "Settings" Windows, then - "Network and Internet", in the section "Proxy server" disable the corresponding item.
