Abstract
An apparatus and method are described for performing content filtering of encrypted network transactions. For example, in one embodiment, for an encrypted Internet transaction (such as an HTTPS transaction), a local cache lookup is performed using the network address of the requested Internet transaction to determine if name resolution data associated with the transaction is stored in a name resolution data cache. If name resolution data associated with the transaction is stored in the name resolution data cache, then the name resolution data is compared with a whitelist of acceptable Internet names. The requested Internet transaction is allowed only if a match is found between the name resolution data and one of the Internet names on the whitelist.
