Netværksproxyi

Netværksproxyi, often translated as network proxies, are intermediary servers that act as a gateway between a user's device and the internet. When a user requests a resource from the internet, the request is first sent to the proxy server. The proxy then forwards the request to the intended destination server on the user's behalf. The response from the destination server is also sent back to the proxy first, which then relays it to the user's device.

There are several types of network proxies, each serving different purposes. Forward proxies are commonly used by individuals or organizations to control internet access, enhance security, or bypass geographical restrictions. They can cache frequently accessed web pages, reducing bandwidth usage and improving loading times. Reverse proxies, on the other hand, are typically deployed in front of web servers to distribute incoming traffic, improve performance, and provide an additional layer of security by hiding the identity and characteristics of the origin servers.

Proxies can offer anonymity by masking the user's original IP address, making it harder for websites to track online activity. They can also be used to filter content, blocking access to certain websites or types of information. In corporate environments, proxies are often employed to enforce security policies and monitor network traffic. However, the use of proxies can also introduce latency and, if not properly configured, can pose security risks themselves.
