iOS HTTPS Proxy

It means a proxy that has no access to the Internet. It is created using special software on the user's computer. Most often it is used to check the performance of the created site or web-application.

Text parsing is the collection of text information, which is then converted either to form a log file or to perform the task set by the developer.

To keep only unique external links while scraping with Scrapy, you can use a set to track the visited external links and filter out duplicates. Here's an example spider that demonstrates how to achieve this:

import scrapy
from urllib.parse import urlparse, urljoin

class UniqueLinksSpider(scrapy.Spider):
    name = 'unique_links'
    start_urls = ['http://example.com']  # Replace with the starting URL of your choice
    visited_external_links = set()

    def parse(self, response):
        # Extract all links from the current page
        all_links = response.css('a::attr(href)').extract()

        for link in all_links:
            full_url = urljoin(response.url, link)

            # Check if the link is external
            if urlparse(full_url).netloc != urlparse(response.url).netloc:
                # Check if it's a unique external link
                if full_url not in self.visited_external_links:
                    # Add the link to the set of visited external links
                    self.visited_external_links.add(full_url)

                    # Yield the link or process it further
                    yield {
                        'external_link': full_url
                    }

        # Follow links to other pages
        for next_page_url in response.css('a::attr(href)').extract():
            yield scrapy.Request(url=urljoin(response.url, next_page_url), callback=self.parse)

- visited_external_links is a class variable that keeps track of the unique external links across all instances of the spider.
- The parse method extracts all links from the current page.
- For each link, it checks if it is an external link by comparing the netloc (domain) of the current page and the link.
- If the link is external, it checks if it is unique by looking at the visited_external_links set.
- If the link is unique, it is added to the set, and the spider yields the link or processes it further.
- The spider then follows links to other pages, recursively calling the parse method.

Remember to replace the start_urls with the URL from which you want to start scraping.

Yes, it is possible to access blocked YouTube or channels unavailable in a certain country using a proxy.

In the settings bar (home screen), select "Network Settings" and then click on Ethernet. Here you should select the "Advanced Settings" option, which contains the "Proxy Server Settings" item. To further configure the proxy, select "Configure Manually", type in the proxy hostname and specify the port. Do not forget to list the domains that the proxy server should not use. You should leave this field empty if it does not exist. If the configuration process is successful, you will see the "Settings saved" notification.
