The invention discloses a cookie access de-emphasis method and apparatus. The method comprises the following steps: reading the configuration information; constructing the mapping list K according to the configuration information; grabbing the network card data packets and analyzing the cookie fields in the network card packets; filtering the cookie fields based on the configuration information; generating a node N; and deleting the expired node in the mapping list K according to the node N and the mapping list K. The technical schemes of the invention can conduct cookie data filtering in the process of data packet transmission, which greatly increases the comparison fields in the cookie access de-duplication and reduces the utilization rate of internal memory.
