Cisco Proxy Server

In UDP communication, there is no built-in mechanism to confirm if the client has received data from the server. UDP is a connectionless protocol, which means it does not establish a connection between the client and server, and therefore, it does not provide any reliability guarantees.

However, there are some techniques you can use to improve the reliability of UDP communication and get an indication that the client has received data:

1. Acknowledgment packets: The server can send acknowledgment packets after sending data to the client. The client can then send acknowledgment packets back to the server after receiving the data. If the server does not receive the acknowledgment packets within a specific timeout period, it can assume that the client has not received the data.

2. Timeout and retransmission: The server can implement a timeout and retransmission mechanism. If the server does not receive an acknowledgment packet within a specific timeout period, it can resend the data and continue to do so until it receives an acknowledgment or reaches a predefined limit.

3. Checksums or hashes: The server can send data along with a checksum or hash value. The client can then calculate the checksum or hash of the received data and compare it with the value sent by the server. If the values match, the client can be confident that it has received the data correctly.

Several virtual proxy servers can be created within one device. These are special dedicated servers that only "service" such traffic. Many devices can connect to them at the same time.

It depends on the purpose for which you plan to work with proxies at all. Personally, one is enough for myself. But if you plan to do massive parsing, it may not be enough to have 100 pieces.

Connect your computer to a functioning router, then open any browser, go to the settings and enable manual configuration. Specify the IP, gateway with DNSI and subnet mask in the appropriate fields. In the "Home network" tab, under "Computers", go to "IPMP Proxy" and turn off this function. Under "System", click on the gear symbol, and under "Components", specify the Proxy UDP HTTP utility and click "Refresh".

Parsing is the collection of all information. Accordingly, parsing a site is copying all of its source code as presented. You can use it to edit the site further or to analyze it for security purposes.
