### 1.7 Other HTTP proxies

I started writing Polipo because the weather was bad. But also because I wanted to implement some features that other web proxies don't have.

- Harvest and Squid: Historic proxies.
- Apache: The web server has a proxy.
- WWWOFFLE: A personal proxy.
- Junkbuster: Get rid of ads.
- Privoxy: Junkbuster on speed.
- Oops: A multithreaded cache.
