Described embodiments may provide systems and methods for matching with indexed Uniform Resource Locator (URL) pattern sets. A device may establish a hash map of patterns. Each pattern may include a suffix of a URL and indexed by a hash of a host prefix of the URL. The hash map of patterns may include a first hash of a first host prefix of a first URL. The device may identify a second URL to match. The second URL may include a second host prefix and a second suffix. The device may calculate a second hash of the second host prefix. The device may determine that the second hash matches an index of the first hash of the hash map. The device may identify, responsive to the determination, a match between a first suffix of the first URL in the hash map and the second suffix of the second URL.

Anchored match algorithm for matching with large sets of URL

An apparatus is provided for detecting the presence of multimedia content in one or more transactions and for classifying the multimedia content in the one or more transactions. The apparatus can include a traffic processor configured to acquire one or more handshake messages associated with the transactions. The apparatus can also include a multimedia detector configured to determine a domain name requested by a specific terminal based on the one or more handshake messages, and to detect the presence of the multimedia content data in the transactions using the determined domain name. The detection of the presence of the multimedia content can be used for at least one of optimizing or reporting of the multimedia content before the multimedia content is provided to the specific terminal.
