Lethe Proxy

Most often it is used to substitute your real IP address. An example of when this is needed: watching shows on Netflix that are only available to US users. A proxy can be used to make a user logging in from anywhere in the world will be identified by the IP address as a US user. Another option is to test your site through a local web server. A proxy in this case is used to intercept all the traffic in order to analyze it further for errors and failures.

There are several ways to speed up a program on Selenium. Here are some tips:

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.

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.

If you intend to use a proxy to work on the Internet, you should first of all clear your browser history. This way, you will get rid of the risk of being identified by past actions on the site. In case you are engaged in Internet promotion, it is also advisable to use proxy servers for this purpose, allowing you to enter different sites safely. This solution will allow you to avoid blocking promoted accounts.
