From the developer: "StayAlive Pro is a program that simulates Internet activity so you do not get disconnected from your ISP. Its features include simulating Internet activity through HTTP or PING, and site access from a random or sequential list. The period between activities can be random or fixed. You can remove the ISP nag window that informs you of being inactive too long. It can stop simulating activity or disconnect at your specified times, and much more.

"Version 2.4 can start Internet activity simulation immediately after program starts. It helps users with broadband connections."
