While web browsing, a computer creates temporary files in a folder, called the cache, of almost every site visited.2 On the opposite end, websites are being saved by entities for purposes of preserving the past. Accordingly, a computer user’s trail may be uncovered by examining the cache. Today’s lawyer and 21st-century pathfinder may discover that the cache is a significant source of evidence. Accordingly, this article addresses issues that may arise in assessing its evidentiary value.
