Warez-BB Proxy

To set up a proxy on your computer, you need to go through a simple procedure. If we're talking about Windows 10, you'll first need to open the "Settings" application and the "Network and Internet" section. Here, after opening the "Proxy Server" tab, find the column "Manual proxy server setup" just to the right and move the switch to the "On" position. Enter the IP address and the proxy port in the specified fields and click "Save".

Here are some general guidelines to approach scraping protected sites:

1. Check Terms of Service:

   • Review the terms of service, robots.txt file, and any other usage policies provided by the website. Some websites explicitly prohibit scraping.

2. Contact the Website Owner:

   • If you have a legitimate reason for scraping and the website provides contact information, consider reaching out to the website owner or administrator to request permission.

3. Use Official APIs:

   • Many websites offer official APIs that allow controlled access to their data. Using an API is a sanctioned and structured way to obtain information.

4. Simulate Human Behavior:

   • Mimic human behavior by setting appropriate headers, handling cookies, and introducing delays between requests. This helps avoid detection mechanisms that may identify automated bots.

5. Handle CAPTCHAs:

   • Some sites may use CAPTCHAs to prevent automated access. Implement mechanisms to handle CAPTCHAs if they are encountered.

6. Use Proxy Servers:

   • Rotate IP addresses using proxy servers to avoid IP-based blocking. However, be aware that some sites may block common proxy server IP ranges.

7. Avoid Aggressive Scraping:

   • Limit the frequency and volume of your requests to avoid overloading the server. Implement rate limiting and throttling to mimic human browsing behavior.

8. Stay Informed:

   • Monitor the website for changes in its structure or policies. Adjust your scraping strategy accordingly to adapt to any modifications.

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.

Technically, a proxy is an ordinary computer or server connected to a network (local or Internet). It accepts traffic from the user, redirects it to the address that was specified in the request. And then receives the response from the server and transmits it to the user's equipment. That is, it is actually an intermediary.

Such proxy redirects requests from clients to different servers (globally or within a single local network). It can be used for load balancing in different Internet services, for testing web applications, for secured access to local network servers (all "non-client" traffic is ignored).
