It means a private proxy server used by several users. For example, one of them has bought a paid proxy and lets his friend use it for a fee. That is, he "shared" his proxy (shared means "common").
The easiest way to set up a home proxy server is to install a router that supports this function. Then get the proxy data (provided by the service in which it is "rented") and enter it in the router settings. If there is no need for a common proxy (for all devices at once), then it should be configured separately for each device with the help of the utilities integrated in the OS for changing the connection properties.
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 organize multi-threaded scraping through a proxy in C#, you can use the HttpClient class along with tasks and threads. Additionally, you may use proxy rotation to avoid rate limiting and bans. Here's a basic example to get you started:
using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Threading.Tasks;
class Program
{
static async Task Main()
{
// List of proxy URLs
List proxyList = new List
{
"http://proxy1.com:8080",
"http://proxy2.com:8080",
// Add more proxies as needed
};
// Create HttpClient instances with a different proxy for each thread
List httpClients = CreateHttpClients(proxyList);
// List of URLs to scrape
List urlsToScrape = new List
{
"https://example.com/page1",
"https://example.com/page2",
// Add more URLs as needed
};
// Create tasks for each URL
List tasks = new List();
foreach (string url in urlsToScrape)
{
tasks.Add(Task.Run(() => ScrapeUrl(url, httpClients)));
}
// Wait for all tasks to complete
await Task.WhenAll(tasks);
// Dispose of HttpClient instances
foreach (HttpClient client in httpClients)
{
client.Dispose();
}
}
static List CreateHttpClients(List proxies)
{
List clients = new List();
foreach (string proxy in proxies)
{
var httpClientHandler = new HttpClientHandler
{
Proxy = new WebProxy(proxy),
UseProxy = true,
};
clients.Add(new HttpClient(httpClientHandler));
}
return clients;
}
static async Task ScrapeUrl(string url, List httpClients)
{
// Select a random proxy for this request
var random = new Random();
var httpClient = httpClients[random.Next(httpClients.Count)];
try
{
// Make the request using the selected proxy
HttpResponseMessage response = await httpClient.GetAsync(url);
// Check if the request was successful
if (response.IsSuccessStatusCode)
{
string content = await response.Content.ReadAsStringAsync();
// Process the content as needed
Console.WriteLine($"Scraped {url}: {content.Length} characters");
}
else
{
Console.WriteLine($"Failed to scrape {url}. Status code: {response.StatusCode}");
}
}
catch (Exception ex)
{
Console.WriteLine($"Error scraping {url}: {ex.Message}");
}
}
}
In this example:
The CreateHttpClients function creates a list of HttpClient instances, each configured with a different proxy from the provided list.
The ScrapeUrl function performs the actual scraping for a given URL using a randomly selected proxy.
The Main method creates tasks for each URL to be scraped and waits for all tasks to complete.
Common users can use proxies to bypass blocking, to protect their personal data and to hide their real IP address or data about the equipment they use. But network administrators use them to analyze network traffic and test web applications.
