CloudShare Proxy

Free proxies, while seemingly profitable and attractive, are actually not very effective. They cannot boast of security, speed, stability and acceptable duration of work. Qualitative and reliable proxies require a certain investment, but they can be obtained from companies that have a good reputation as proxy service providers. You can also find out about all the nuances of proxy selection with the help of special proxy databases.

A firewall is responsible for filtering packets of traffic. For example, it blocks access to the Internet for certain applications. There are many more options for using a proxy. But if you install special software, it can also be used for such purposes.

If you can't download images in Scrapy:

- Check the image pipeline configuration in settings.py.
- Verify HTTPS compatibility and install the certifi package if necessary.
- Confirm the correctness of XPath or CSS selectors for image URLs.
- Ensure image URLs are in the correct format; log URLs for inspection.
- Handle redirects by setting REDIRECT_ENABLED = True.
- Check and set appropriate HTTP headers in your Scrapy spider.
- Adjust the CONCURRENT_REQUESTS setting to avoid server restrictions.
- Verify correct configuration of the ImagesPipeline.
- Inspect the downloaded images in the specified IMAGES_STORE directory.
- Implement exception handling in your spider to catch download errors.

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 connect to the Internet through a proxy server, you must authenticate with your username and password. This can be done by logging in automatically, by using a Windows agent, and by using a Web agent. With automatic login, as well as when using the Web-agent, you need to manually configure the address of the proxy server in your browser. The Windows agent does not require any special settings, because it sets up everything you need for work by itself.
