SWPS 4.0 and Squid

Last day we needed to come up with some quick data on how proxy 4.0 compares with Squid, for an internal requirement. Soon a couple of facts became apparent - architecture-wise, proxy 4.0 is miles ahead as compared to squid, not to mention stability, user friendliness, simplicity, etc. But feature-wise, proxy 4.0 does not quite match up to Squid.

It's by no means a comprehensive one, and i admit that it's been a rush job. I have left out the negative points due to two reasons - that's what the requirement demanded, and, the negative list would mostly be a list of features that Squid has and proxy 4.0 doesn't. Anyway.
