Cache database hotspot data identification method and system

The invention provides a cache database hotspot data identification method and system, a first server creates a Hash chain table for a client when establishing a Session, the Hash chain table stores a Hash value of a webpage address, the number of times of accessing a webpage and the residence time on the webpage, and the Hash chain table is destroyed along with the destruction of the Session; the first server regularly traverses all Sessions on the first server, sends the Hash chain table corresponding to the Sessions in the validity period to the second server, and empties the Hash chain table after the Hash chain table is sent; the second server preprocesses the Hash chain table, N webpage addresses with the most access times are obtained through analysis according to the preprocessed Hash chain table, and the second server obtains hotspot data according to the N webpage addresses and informs the cache database of loading the hotspot data to the cache database. According to the method and the device, the h
