Proxy servers have the following main functions:
- Using cache, they can speed up access to a website by storing the pages after the first visit. On later visits, the cache versions are used instead of the web server.
- Keep your identity (IP address) secret, accessing the internet via the proxy identity.
- Can serve as an additional firewall, providing greater protection from online threats.
- Allows internet traffic to be filtered, enabling the blocking of individual websites.
