pfSense Reverse Proxy

In the "System Settings" section, open the "Network" tab, and then, when you highlight the active connection, click "Advanced". Here, in the "Proxies" tab, tick only the HTTP proxy if you do not intend to use other types of proxies temporarily. Enter the address of your proxy server and its port in the designated fields and click "OK".

If you're encountering issues with parsing escaped backslashes in JSON, it's important to understand how JSON handles escape characters. In JSON, a backslash (\) is an escape character, and certain characters must be escaped to represent them in strings.

If you're working with a string that includes escaped backslashes and you want to properly parse it, make sure the JSON string itself is correctly formatted. Below is a general guide on how to handle escaped backslashes in JSON parsing:

1. Correct JSON Format:

Ensure that the JSON string is correctly formatted, and the backslashes are properly escaped. For example:

{
  "path": "C:\\Program Files\\Example"
}

In this example, the backslashes in the path are escaped with an additional backslash.

2. JSON Unmarshalling in Go:

If you're working with JSON parsing in Go (Golang), use the encoding/json package to unmarshal the JSON data into a Go struct.

Example:

package main

import (
	"encoding/json"
	"fmt"
)

type MyStruct struct {
	Path string `json:"path"`
}

func main() {
	jsonData := `{"path": "C:\\Program Files\\Example"}`

	var myStruct MyStruct
	err := json.Unmarshal([]byte(jsonData), &myStruct)
	if err != nil {
		fmt.Println("Error:", err)
		return
	}

	fmt.Println("Path:", myStruct.Path)
}

In this example, the backslashes in the JSON string are properly escaped, and the json.Unmarshal function is used to parse the JSON into a Go struct.

3. Manual Handling:

If you're working with JSON data in another language or context, make sure your JSON parser correctly handles escape characters. Some JSON parsers automatically handle escape characters, while others may require manual handling.

In Node.js, you can introduce delays in your scraping logic using the setTimeout function, which allows you to execute a function after a specified amount of time has passed. This is useful for implementing delays between consecutive requests to avoid overwhelming a server or to comply with rate-limiting policies.

Here's a simple example using the setTimeout function in a Node.js script:

const axios = require('axios'); // Assuming you use Axios for making HTTP requests

// Function to scrape data from a URL with a delay
async function scrapeWithDelay(url, delay) {
  try {
    // Make the HTTP request
    const response = await axios.get(url);

    // Process the response data (replace this with your scraping logic)
    console.log(`Scraped data from ${url}:`, response.data);

    // Introduce a delay before making the next request
    await sleep(delay);

    // Make the next request or perform additional scraping logic
    // ...

  } catch (error) {
    console.error(`Error scraping data from ${url}:`, error.message);
  }
}

// Function to introduce a delay using setTimeout
function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

// Example usage
const urlsToScrape = ['https://example.com/page1', 'https://example.com/page2', 'https://example.com/page3'];

// Loop through each URL and initiate scraping with a delay
const delayBetweenRequests = 2000; // Adjust the delay time in milliseconds (e.g., 2000 for 2 seconds)
for (const url of urlsToScrape) {
  scrapeWithDelay(url, delayBetweenRequests);
}

In this example:

• The scrapeWithDelay function performs the scraping logic for a given URL and introduces a delay before making the next request.
• The sleep function is a simple utility function that returns a promise that resolves after a specified number of milliseconds, effectively introducing a delay.
• The urlsToScrape array contains the URLs you want to scrape. Adjust the delay time (delayBetweenRequests) based on your scraping needs.

Please note that introducing delays is crucial when scraping websites to avoid being blocked or flagged for suspicious activity.

Encrypting a UDP connection with TLS is not directly possible, as TLS is designed to work with TCP connections. However, you can use Datagram TLS (DTLS) or Secure Reliable Datagram (SRD) to achieve a similar result. DTLS is an extension of TLS that works with UDP, while SRD is a protocol that provides secure and reliable datagrams over UDP.

Here's an example of how to encrypt a UDP connection with DTLS using the Crypto++ library in C++:

1. First, install the Crypto++ library on your system. You can find the installation instructions at: https://www.cryptopp.com/wiki/Installing

2. Create a new C++ project and include the necessary Crypto++ headers.

3. Define the necessary structures and classes for DTLS:

#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 

4. Implement the DTLS handshake and data exchange:

int main()
{
    try
    {
        CryptoPP::AutoSeededRandomPool rng;

        // Generate a DTLS context
        CryptoPP::DTLS_Context dtlsContext(CryptoPP::DTLS_CLIENT);

        // Set up the DTLS context
        dtlsContext.SetPeerCertVerificationCallback(
            [](const CryptoPP::DTLS_PeerCertificate& peerCert, int& errorCode) -> bool
        {
            // Verify the peer certificate
            // Return true if the certificate is valid, false otherwise
        });

        // Perform the DTLS handshake
        dtlsContext.StartHandshake();

        // Send data over the encrypted UDP connection
        std::string data = "Hello, secure UDP!";
        std::vector encryptedData;
        dtlsContext.Encrypt(data.data(), data.size(), encryptedData);

        // Receive data over the encrypted UDP connection
        std::vector receivedData(encryptedData.size());
        dtlsContext.Decrypt(receivedData.data(), receivedData.size(), encryptedData);

        // Convert the received data to a string
        std::string receivedString(receivedData.begin(), receivedData.end());

        // Output the received data

To get a token from local storage, you can use the JavaScript localStorage object, which allows you to store key-value pairs in the browser's local storage. Here's how to get a token from local storage:

Access the token: You can access the token stored in local storage by using the localStorage.getItem() method. This method takes a key as an argument and returns the value associated with that key.

For example, if you have stored a token with the key "authToken", you can retrieve it like this:

const token = localStorage.getItem("authToken");

Use the token: Once you have the token, you can use it in your application as needed. For example, you can include it in the Authorization header of your API requests:

const headers = {
  "Authorization": `Bearer ${token}`,
  // other headers...
};

Remember that local storage is limited to string values, so if your token is an object or has special characters, you might need to encode or serialize it before storing it and then decode or deserialize it when retrieving it.
