Click bot w/IP spoofing

Hey there coders, I need a bot that will access my site by spoofing the referring IP and user-agent from lists I will provide. The bot should also click on internal links a number of times (ex:2-4 pages per visit) and stay on the site for a specific length of time (ex:between 2 and 4 minutes). I should also be able to define a bounce rate (ex:20%). I am looking for a multi-threaded solution that will run on a linux or windows server. Thanks and happy bidding! P.S. I found this IP spoofing information that you might find useful: <[login to view URL]>
