Proxy for MM3-ProxySwitch

The main task of these two popular technologies is to provide security for the Internet user. Despite a certain similarity of tasks, they are performed absolutely differently. Proxy, although it allows you to remain anonymous and bypass blocked sites, it is still quite vulnerable, especially when it comes to untested services. VPN in this regard looks preferable, because thanks to end-to-end encryption it reliably protects information from the entry point to the exit point.

When scraping data from a website, it's common to encounter empty strings or strings that consist only of whitespace. To get rid of these empty or whitespace-only strings, you can use various approaches depending on the programming language you're using. Below are examples in Python and JavaScript.

Python:

# Example list containing strings with some empty or whitespace-only strings
data = ["apple", "", "  ", "banana", "  ", "cherry", ""]

# Remove empty and whitespace-only strings using list comprehension
filtered_data = [s.strip() for s in data if s.strip()]

# Print the filtered data
print(filtered_data)

In this example, s.strip() is used to remove leading and trailing whitespace from each string, and if s.strip() is used to filter out empty and whitespace-only strings.

JavaScript:

// Example array containing strings with some empty or whitespace-only strings
const data = ["apple", "", "  ", "banana", "  ", "cherry", ""];

// Remove empty and whitespace-only strings using filter and trim
const filteredData = data.filter(s => s.trim() !== "");

// Log the filtered data
console.log(filteredData);

In JavaScript, s.trim() is used to remove leading and trailing whitespace, and s.trim() !== "" is used as a condition in the filter function to exclude empty and whitespace-only strings.

In Selenium, you can add headers to your web requests using the webdriver.ChromeOptions class. This is useful when you want to simulate certain HTTP headers in your Selenium-driven browser. Here's an example of how to add headers to Selenium using the Chrome WebDriver:

from selenium import webdriver

# Create ChromeOptions object
chrome_options = webdriver.ChromeOptions()

# Add headers to the options
chrome_options.add_argument("--disable-blink-features=AutomationControlled")  # Example header

# Instantiate the Chrome WebDriver with options
driver = webdriver.Chrome(options=chrome_options)

# Now you can use the driver for your automation tasks
driver.get("https://example.com")

# Close the browser window when done
driver.quit()

In this example, we use the add_argument method of ChromeOptions to add headers. The specific argument --disable-blink-features=AutomationControlled is an example of a header that might be used to mitigate detection mechanisms that check for automation.

You can customize the headers by adding more add_argument calls with the desired headers. Here's an example of adding custom headers:

chrome_options.add_argument("user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36")
chrome_options.add_argument("accept-language=en-US,en;q=0.9")
# Add more headers as needed

Remember to adapt the headers based on your requirements and the website you are interacting with. The headers you add should mimic those of a regular user to reduce the chances of detection.

A proxy server acts as an intermediary between the client and the requested Internet resource. It is assigned the role of a kind of gateway or filter, which is responsible for submitting a request, receiving the required information and providing it to the user. The proxy server, if necessary, can make changes in incoming and outgoing data, the nature of which will depend on the type of proxy and its settings.

In Key Collector settings, the user can specify parameters of the proxy server through which the program will connect to the network. In the application window, first select "Settings", then go to the "Network" tab and check "Use proxy". Its parameters can be set either manually or through a configuration file.
