Skyhigh Proxy

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.

To address the "ERROR conda.core.link:_execute(637)" issue when installing Scrapy (Python 3.7) on Windows 8:

- Update conda: conda update conda
- Create a new virtual environment: conda create -n myenv python=3.7 and then conda activate myenv
- Install Scrapy using conda: conda install scrapy
- Check Python version compatibility with Scrapy.
- Alternatively, try installing Scrapy using pip: pip install scrapy
- Update Anaconda: conda update anaconda
- Temporarily disable antivirus/firewall.
- Verify network connection stability.
- If issues persist, seek assistance from community forums or provide more details for further help.

In Scrapy, you can control the caching behavior of requests made by rules in your spider by adjusting the dont_cache attribute in the Rule object. The dont_cache attribute, when set to True, indicates that the requests matched by the rule should not be cached.

Here's an example of how you can use dont_cache in a CrawlSpider:

from scrapy.linkextractors import LinkExtractor
from scrapy.spiders import CrawlSpider, Rule

class MySpider(CrawlSpider):
    name = 'my_spider'
    allowed_domains = ['example.com']
    start_urls = ['http://example.com']

    rules = (
        # Example Rule with dont_cache set to True
        Rule(LinkExtractor(allow=('/page/')), callback='parse_page', follow=True, dont_cache=True),
    )

    def parse_page(self, response):
        # Your parsing logic for individual pages goes here
        pass

- The spider is defined as a CrawlSpider.
- The Rule is created with LinkExtractor to match URLs that contain '/page/' in them.
- The dont_cache=True attribute is set to True in the Rule, indicating that requests matched by this rule should not be cached.

By setting dont_cache to True, Scrapy will make sure that requests matched by this rule will be fetched without considering the cache. This is useful when you want to ensure that each request to the specified URLs results in a fresh response, bypassing any cached data.

A proxy server passes all traffic through itself, acting as an intermediary between the user and the remote server. It is most often used to conceal the real IP, to conditionally change the user's location, or to analyze traffic (for example, when testing web applications).

And it depends on what purpose the proxy is used for. But you should definitely give preference to paid proxies. They are more reliable, always available, and with that comes a guarantee of privacy. Unfortunately, personal data is often stolen from free proxies.
