ELI5 Proxy

Connect your computer to a functioning router, then open any browser, go to the settings and enable manual configuration. Specify the IP, gateway with DNSI and subnet mask in the appropriate fields. In the "Home network" tab, under "Computers", go to "IPMP Proxy" and turn off this function. Under "System", click on the gear symbol, and under "Components", specify the Proxy UDP HTTP utility and click "Refresh".

In Selenium with Python, you can set the name of the downloaded file by using the set_preference() method on the Options object before initializing the WebDriver. Here's an example using Chrome:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

# Set the path to the ChromeDriver executable
chrome_driver_path = "path/to/chromedriver"

# Set the preference to save downloaded files with a specific name pattern
options = Options()
options.add_argument("download.default_directory='path/to/download/folder'")
options.add_argument(f"download.download_path='path/to/download/folder'")
options.add_preference("download.filename_template", "%f - %r")

# Initialize the Chrome WebDriver with the specified options
driver = webdriver.Chrome(executable_path=chrome_driver_path, options=options)

# Your Selenium code goes here

# Close the browser
driver.quit()

Replace path/to/chromedriver, path/to/download/folder, and %f - %r with the appropriate values for your setup. The %f placeholder is replaced by the file name, and the %r placeholder is replaced by the original file name.

This example sets the download directory and the filename template for downloaded files. When a file is downloaded, it will be saved with a name that includes the original file name and a unique identifier, separated by a dash.

Keep in mind that this approach sets the download preferences for the entire browser session. If you need to change the download preferences for a specific test, you can set them before the test runs and reset them afterward.

A proxy server script address, also known as a proxy script or proxy URL, is a specific address that points to a script or a web page containing instructions for connecting to a proxy server. This script or web page can be written in various programming languages, such as PHP, Perl, or Python, and it typically contains the configuration settings and parameters required to connect to a proxy server.

When you visit a website or access an online resource, your browser or application may use a proxy server to route your traffic. In some cases, you might need to manually configure your browser or application to use a specific proxy server. To do this, you would need the proxy server's script address, which you can then enter into the appropriate settings field.

For example, you might encounter a proxy server script address in the following format:

http://:@:/

Here, and represent the proxy server's authentication credentials, is the proxy server's IP address or hostname, is the proxy server's port number, and is the path to the proxy script on the proxy server.

A firewall is responsible for filtering packets of traffic. For example, it blocks access to the Internet for certain applications. There are many more options for using a proxy. But if you install special software, it can also be used for such purposes.

A DNS server is a remote computer that receives a domain request from a user device. And it converts it into an IP address. Sometimes it is through the DNS-server that ISPs block sites. And DNS-proxy, respectively, allows you to bypass these restrictions completely.
