[squid-users] Squid configuration query

Sir,
     We need to configure squid for our environment . I'm giving the requirement
1. we have the domain in windows 2008 and have to authenticate the users in it
2. we have to limit the total usage of browsing time of the day for
user (eg. user1 can use 1hrs each day, user 2 can use 2 hrs each day)
3. we have to limit the download limit of the day for user (eg. user1
can download 100 mb each day, user 2 can download 1GB each day)

          We can user linux as well as windows for internet server
but domain server cant be changed that must be windows server 2008.
Please suggest which server flavour should i use(Linux or Windows)

           Please advice me ang give me the documentation for the same
. I'm looking your favourable reply
