Explain the following terms
Caching - Proxy servers can cache (make a copy and store it on the server) commonly used web pages so the server doesn't have to access the internet and download the page every time someone on the network wants it.
- Ip masking
- The proxy server essentially replaces a computer's IP address with the address of the proxy server making it appear as if an internet request originated from the proxy server even though it didn't.
- Logging

- Filtering
- Filtering is a process that allows network administrators to deny access to certain urls and IP addresses to any or all clients in the network

- Contain databases with the locations of top-level domains
- What is primary
- Keeps track of wen sites with the top-level domains
- What is scondary
