I recently came across a new patent, does anyone know the impact of the following patent on squid? http://tinyurl.com/ym7xq8 US 7,103,794 B2 It speaks about network cache objects in a general form and appears to apply to Squid. The key claim is "receiving a set of network objects in response to a first request to a server from a client; and maintaining said network objects in a cache memory in a cache engine, said cache engine connected via a network to the server and the client, said cache memory including mass storage; wherein said step of mainting includes steps of recording said network objects from said cache memory, so as to substantially minimizes a time required for retrieving said network objects from said mass storage. " There are a series of other cliams that also appear to apply. The filing date predates squid version 2.0, but I hope Squid version 1 contains software that is considered prior art and renders Squid immune. A quick search through the archives shows that Squid has dealt with other claims in the past. Bob Ault
