What is proxy king?

As an AI language model, I am not aware of any known entity called "Proxy King". However, a proxy server or a proxy king is a computer system or software application that acts as an intermediary for requests from clients seeking resources from other servers. A proxy server may either receive requests from clients seeking resources such as a web page, file, or other resource available from another server and forward the request to the appropriate server; or, it may simply cache items locally to reduce latency or improve performance. Proxy servers are commonly used in corporate networks to improve security and filter out unwanted traffic. There are many proxy provider companies operating in the market that offer proxy services to individuals and organizations.
