Proxy/Caching Servers

[Jon Lyons <jlyons30 () yahoo com>]

  Hey all, 
 
 I need some recommendations on proxy servers for enterprise environments. Our current product can't handle the load & 
is no longer being supported by the vendor. The devices need to handle at least 1000+ concurrent connections at about 
20 Mbit/s. Websites, Streaming, etc, etc…
 
 Not sure if there's one product that does what I'm looking for: 
 
 1. Appliance based (preferred, but not required) 
 2. Clusterable/VRRP Setup or can be used behind a load balancer
 3. Web/FTP virus checking
 4. Caching
 5. Web content filtering (include ability to add manually to a deny list)
 6. Logging and user auditing (via name or client IP address)
 7.  Real-time traffic monitoring
 8. Grant/Deny access to particular websites from individual/grouped client IP addresses
    Thanks
