You need to open the settings menu, go to "Data and disk", and then - "Proxy settings". There you can enter the address, port number of the intermediate server, as well as username and password for authorization (if necessary).

To parse all pages of a website in Python, you can use web scraping libraries such as requests for fetching HTML content and BeautifulSoup or lxml for parsing and extracting data. Additionally, you might need to manage crawling and handle the structure of the website.

Here's a basic example using requests and BeautifulSoup:

import requests
from bs4 import BeautifulSoup
from urllib.parse import urljoin, urlparse

def get_all_links(url):
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
    
    # Extract all links on the page
    links = [a['href'] for a in soup.find_all('a', href=True)]
    
    return links

def parse_all_pages(base_url):
    all_links = get_all_links(base_url)
    all_pages_content = []

    for link in all_links:
        # Form the full URL for each link
        full_url = urljoin(base_url, link)

        # Ensure the link is within the same domain to avoid external links
        if urlparse(full_url).netloc == urlparse(base_url).netloc:
            # Get HTML content of the page
            page_content = requests.get(full_url).text
            all_pages_content.append({'url': full_url, 'content': page_content})

    return all_pages_content

# Example usage
base_url = 'https://example.com'
all_pages_data = parse_all_pages(base_url)

# Now you have a list of dictionaries with data for each page
for page_data in all_pages_data:
    print(f"URL: {page_data['url']}")
    # Process HTML content of each page as needed
    # For example, you can use BeautifulSoup for further data extraction

This example fetches all links from the initial page and then iterates through each link, fetching and storing the HTML content of the linked pages. Make sure to handle relative URLs and filter external links based on your requirements.

To find an element by its HTML code in Selenium, you can use the ExecuteScript method to execute JavaScript code that returns the element corresponding to the provided HTML code. Here's an example of how to do this using C#:

Install the required NuGet packages:

Install-Package OpenQA.Selenium.Chrome.WebDriver -Version 3.141.0
Install-Package OpenQA.Selenium.Support.UI -Version 3.141.0

Create a method to find an element by its HTML code:

using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;
using System;
using System.Text.RegularExpressions;

public static IWebElement FindElementByHtml(this IWebDriver driver, string htmlCode)
{
    // Execute JavaScript to create a new element with the provided HTML code
    var script = $@"var div = document.createElement('div'); div.innerHTML = arguments[0]; document.body.appendChild(div); return div.children[0];";
    var element = (IWebElement)driver.ExecuteScript(script, htmlCode);

    // Remove the created element from the DOM
    driver.ExecuteScript("document.body.removeChild(document.body.children[document.body.children.length - 1]);");

    return element;
}

Use the FindElementByHtml method in your test code:

using OpenQA.Selenium;
using System;

namespace SeleniumFindElementByHtmlExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Set up the WebDriver
            IWebDriver driver = new ChromeDriver();
            driver.Manage().Window.Maximize();

            // Navigate to the target web page
            driver.Navigate().GoToUrl("https://www.example.com");

            // Find an element by its HTML code
            IWebElement element = driver.FindElementByHtml(@"
                

                    
Example Heading
                    
Example paragraph text.
                
");

            // Perform any additional actions as needed

            // Close the browser
            driver.Quit();
        }
    }
}

In this example, we first create a method called FindElementByHtml that takes an IWebDriver instance and a string containing the HTML code as input. Inside the method, we use the ExecuteScript method to execute JavaScript code that creates a new element with the provided HTML code, appends it to the document body, and returns the created element.

We then remove the created element from the DOM using another ExecuteScript call. The method returns the created element as an IWebElement.

In the test code, we set up the WebDriver, navigate to the target web page, and use the FindElementByHtml method to find an element by its HTML code. After finding the element, you can perform any additional actions as needed.

Remember to replace the HTML code in the FindElementByHtml method call with the actual HTML code you want to use.

The basic configuration is written in nginx.conf file in the program directory. You need to create a server article and specify there the port number and the place for cached data. Thus, for example, by using port 8080 you may organize a local proxy to test your own sites.

Regular Windows functionality has a minimum of settings for proxies. Therefore, it is recommended to use third-party applications for this purpose. For example, Proxy Switcher or Proxifier. There you can not only set the server characteristics but also, for example, create a folder for packets of traffic that are transmitted through the local network.
