Google Scholar Proxy

After editing is complete, the proxy must be disabled in order to send the video for color correction. To do this, select all the proxies in the project window and choose the "Switch offline" command from the context menu. Then, after making sure that the "Media files remain on disk" option is active, click "Ok". If after that the program monitor window is filled with red color, do not be frightened, it is normal.

Proxy servers are of the following types:
FTP proxy designed to send data to FTP servers.
CGI proxy, which is used to browse web services in a browser. You do not need to configure any settings. All actions are performed anonymously. Often such proxies are designed in the form of a page where you have to specify the address of a desired site.
SMTP, POP3 and IMAP proxy are designed for sending and receiving email.
HTTP and HTTPS proxies are for scrolling web services.
Socks proxy are used as an anonymizer. No one will know about the user's actions.

To deactivate the proxy server on Windows 10, you need to perform the following steps:
Open the "Windows Settings" menu.
Go to the "Network and Internet" tab.
Open the "Proxy Server" section.
Deactivate the "Use setup script" option.
Deactivate "Use proxy server" option. Reboot your computer. If the proxy server option has not been disabled, deactivate the "Define parameters automatically" option in the "Proxy server" section. After that you have to restart your PC again.

A server proxy is software installed on a computer on a network that allows you to make requests to other computers on your behalf. A server proxy is a kind of intermediary that ensures the secure exchange of data.

It seems there might be a confusion in your request. Polly is a resilience and transient-fault-handling library in C# for dealing with issues like network failures, timeouts, and other transient errors. It is not directly related to parsing courses or web scraping.

If you are looking to parse a course from a website using C#, you might want to use a combination of HTTP requests and HTML parsing libraries. Here's a basic example using the HtmlAgilityPack library for HTML parsing and HttpClient for making HTTP requests

Install HtmlAgilityPack:

You can install the HtmlAgilityPack library using NuGet Package Manager Console:

Install-Package HtmlAgilityPack

Example Code

Here's a simple example of how you might use HttpClient and HtmlAgilityPack to parse course information from a website:

using System;
using System.Net.Http;
using HtmlAgilityPack;

class Program
{
    static async System.Threading.Tasks.Task Main(string[] args)
    {
        // URL of the course page
        string courseUrl = "https://example.com/courses";

        // Make an HTTP request to get the HTML content
        using (HttpClient client = new HttpClient())
        {
            string htmlContent = await client.GetStringAsync(courseUrl);

            // Use HtmlAgilityPack to parse the HTML
            HtmlDocument doc = new HtmlDocument();
            doc.LoadHtml(htmlContent);

            // Extract course information (modify as per the HTML structure)
            HtmlNodeCollection courseNodes = doc.DocumentNode.SelectNodes("//div[@class='course']");
            if (courseNodes != null)
            {
                foreach (HtmlNode courseNode in courseNodes)
                {
                    string courseTitle = courseNode.SelectSingleNode(".//h2")?.InnerText.Trim();
                    string courseDescription = courseNode.SelectSingleNode(".//p")?.InnerText.Trim();

                    Console.WriteLine($"Title: {courseTitle}");
                    Console.WriteLine($"Description: {courseDescription}");
                    Console.WriteLine();
                }
            }
            else
            {
                Console.WriteLine("No course information found on the page.");
            }
        }
    }
}

This is a basic example, and you'll need to adapt it based on the actual HTML structure of the course page you are working with.
