Embodiments disclosed herein relate to systems and methods for providing a smart cache. In embodiments, a variable time to live (TTL) may be calculated and associated with data as it is stored in a cache. The variable TTL may be calculated based upon reputation and/or category information related to the source of the data. The reputation and/or category information may include TTL modifiers for adjusting the TTL for data from a particular data source that is stored in the cache. In further embodiments, a feedback method may be employed to update reputation and/or category information for a particular data source.
