For ISPs, this leads to bad user experience with internet performance resulting inincreased demands to improve theweb’s infrastructure. But expanding without any solutions will result in server overload and unacceptable service response times. To combat these issues, internet accelerator companies have come up with caching solutions that pre-fetch user details to speed up the performance of the internet.
