Enterprise proxy server

in Security+
Looking for answers of two questions
1. What are top 5 or 10 most widely used Proxy server in Enterprise world
2. Can we categorized them into some subset. To give more context, I have a httpclient, given some parameter it can traverse through the proxy server to estabilsh a connection . I wanted to check if it can work with most of the proxy server, which all proxy server should I test to have minimum risk.
Thanks,
VC

Websense and squid are quite popular, in terms of Enterprise i would go for websense.
As @Expect mentioned, Squid and Websense are good. I believe F5's Big-IP can transparent forward proxy, along with Apache, Nginx, and probably some other web server setups as well.
I would do your testing with Squid. It's easy to setup, easy to use, and commercial products should be able to do everything Squid does.
