Abstract: A method for HTTP protocol-based data request includes: receiving an HTTP request from a downstream connection, associating the HTTP request with an upstream connection, converting the HTTP request into a data frame, transmitting the data frame through the associated upstream connection, collecting response data from the upstream connection, mapping the response data to the associated HTTP request, and returning the response data to the downstream connection where the HTTP request is located.

Abstract: The present disclosure provides a method and system for performing an SSL Handshake. In the method, during an SSL handshake with a target terminal, a target CDN node determines a target service server accessed by the target terminal and obtains information to be processed by a private key; the target CDN node sends a private key processing request to a private key server corresponding to the target service server, the private key processing request carries the information to be processed and target private key processing type information; the private key server processes the information to be processed based on the target private key processing type information and a private key of the target service server and sends a processing result to the target CDN node so that the target CDN node may continue to perform the SSL handshake with the target terminal according to the processing result.
