In this chapter, we learned about Untangle Bandwidth Control and Web Cache and saw how they can save your network bandwidth and optimize its usage. Bandwidth Control is used to set priority for the traffic based on its criteria. Any violience traffic can be limited or can get a certain quota. The Web Cache is used to cache the static contents of the visited web sites; thus, when rerequested, it can serve it from the cache instead of redownloading it, which will save bandwidth and time.

In the next chapter, we'll cover how we can provide different rules for different users; for example, senior staff will get access to Facebook while the remaining staff won't. In addition, we can set time-based policies such as allowing Facebook during the dinner time and block it otherwise.
