K8s Apiserver Proxy

VPN is considered a more advanced technology for anonymization on the Internet. The main (but not the only) difference between VPN is the encryption of all traffic. But this decreases the connection speed and also increases the response time of the remote server. A proxy works slightly faster in this respect.

Under such parsing we mean the collection of keywords from services such as Yandex Wordstat. These data will later be required for SEO-promotion of the site. The resulting word combinations are then integrated into the content of the resource, which improves its position in SERPs on a particular topic.

To send a user class object over UDP, you will need to serialize the object into a format that can be transmitted over the network. Here's a step-by-step guide on how to do it in Python:

1. Import necessary libraries:

import pickle
import socket

2. Define your user class:

class User:
    def __init__(self, name, age):
        self.name = name
        self.age = age

3. Serialize the user object using pickle:

def serialize_user(user):
    return pickle.dumps(user)

4. Create a UDP socket:

def create_udp_socket(host, port):
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    sock.bind((host, port))
    return sock

5. Send the serialized user object over UDP:

def send_user(sock, user, host, port):
    serialized_user = serialize_user(user)
    sock.sendto(serialized_user, (host, port))

6. Putting it all together:

if __name__ == "__main__":
    user = User("John Doe", 30)
    host, port = "127.0.0.1", 12345
    sock = create_udp_socket(host, port)
    send_user(sock, user, host, port)

On the receiving side, you will need to deserialize the received data using pickle and create a new user object from it.

If you can't proxy requests in Scrapy:

- Verify correct proxy configuration in Scrapy settings.
- Confirm proxy functionality with external tools.
- Check for typos or errors in your code and settings.
- Ensure proxy authentication details are correct.
- Test with a direct internet connection to isolate the issue.
- Check for IP blocking by the target website.
- Confirm proper configuration of the HttpProxyMiddleware.
- Use Scrapy logging to inspect requests and responses.
- Ensure your proxy supports HTTPS if needed.
- Test with a single, static proxy for simplicity.
- Keep Scrapy and dependencies up to date.
- Consider using middleware libraries like scrapy-rotating-proxies.

Paid proxies are definitely better and more reliable than free ones. How do you test them? You can simply use the Hidemy Name service. It also shows which protocols the service uses and how reliable the connection is.
