Unlimited Residential Proxy

The easiest option is to use ready-made online proxy checkers. For example, Hidemy.name, which shows the type of protocol used. Or you can simply run Speedtest - this will show you the bandwidth and response speed (ping).

If you're working with Spring Boot in Java and need to parse JSON with multiple attachments, you might be dealing with a scenario involving HTTP requests with JSON payload and file attachments. In this case, you can use @RequestPart in your controller method to handle JSON and multipart requests.

Here's a basic example

Create a DTO (Data Transfer Object) class:

public class RequestDto {
    private String jsonData;
    private MultipartFile file1;
    private MultipartFile file2;

    // getters and setters
}

Create a controller with a method to handle the request:

import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestPart;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

@RestController
@RequestMapping("/api")
public class ApiController {

    @PostMapping("/processRequest")
    public ResponseEntity processRequest(@RequestPart("requestDto") RequestDto requestDto,
                                                @RequestPart("file1") MultipartFile file1,
                                                @RequestPart("file2") MultipartFile file2) {
        // Process JSON data in requestDto and handle file attachments
        // ...

        return ResponseEntity.ok("Request processed successfully");
    }
}

3. Send a multipart request with JSON and attachments:

Using tools like Postman or curl, you can send a multipart request. Here's an example using Postman:

• Set the request type to POST.
• Set the URL to http://localhost:8080/api/processRequest.
• Under the "Body" tab, select "form-data".
• Add three key-value pairs:
  • Key: requestDto, Value: {"jsonData": "your_json_data"}
  • Key: file1, Value: select a file
  • Key: file2, Value: select another file

Make sure you have the appropriate dependencies in your project for handling multipart requests. If you're using Maven, you can include the following dependency in your pom.xml:

    org.springframework.boot
    spring-boot-starter-web

Adjust the example based on your specific use case and the structure of your JSON data. The key point is to use @RequestPart to handle both JSON and file attachments in the same request.

Working through a proxy involves routing your internet traffic through a proxy server, which acts as an intermediary between your device and the internet. This can be done for various reasons, such as improving security, privacy, or accessing content that may be restricted in your location. Here's how to work through a proxy:

Obtain a proxy server: First, you need to find a proxy server that meets your needs. You can find proxy servers through online directories or by asking for recommendations from friends, family, or online communities. Make sure to choose a reliable and trustworthy proxy server.

Configure your device or browser: Once you have a proxy server, you need to configure your device or browser to use the proxy. The process varies depending on the device and browser you're using.

Creating your own proxy server can be a complex process that requires knowledge of networking, programming, and server management. However, if you're interested in setting up a proxy server, here's a general outline of the steps you'll need to follow:

1. Choose a server: You'll need a dedicated server or a computer to act as your proxy server. Make sure the server has a stable internet connection and sufficient resources (RAM, storage, and bandwidth) to handle the traffic.

2. Install an operating system: Install a suitable operating system on your server, such as Linux (e.g., Ubuntu, CentOS, or Debian).

3. Configure the server: Set up your server by configuring the firewall, routing, and network settings. You may need to edit configuration files or use command-line tools to make these changes.

4. Install a proxy server software: Choose a proxy server software or platform to run on your server. Some popular options include Squid, Privoxy, and Caddy. Install the software using the package manager for your operating system (e.g., apt-get for Debian-based systems or yum for CentOS-based systems).

5. Configure the proxy server: Open the configuration file for your proxy server software (usually a text file) and edit the settings to match your requirements. You'll need to configure the listening port, IP addresses to forward requests to, and other settings such as authentication, logging, and caching.

6. Test the proxy server: Once you've configured the proxy server, test it to ensure it's working correctly. You can use online tools or test it with your web browser by configuring the browser to use your proxy server.

7. Secure the proxy server: Implement security measures to protect your proxy server from unauthorized access and potential attacks. This may include setting up a firewall, using strong authentication, and keeping the server software up to date with the latest security patches.

8. Maintain and monitor: Regularly monitor the performance and security of your proxy server, and perform routine maintenance tasks such as updating software, checking logs, and ensuring sufficient resources are available.

There are special online services that use IP and HTTP connection tags to determine if a proxy is being used from your equipment. The most popular are Proxy Checker, Socproxy.
