Specifically, the terminal proxy server receives an Http request sent by the terminal through a TCP connection.
Step S12: and searching the address information of the server proxy server corresponding to the server in a preset address scheme table by using the address information of the server in the Http request.
Specifically, the Http request includes address information of the target server, and the terminal proxy server stores a pre-established address scheme table, where the address scheme table records address information of the server, address information of the server proxy server, and a correspondence between the server and the server proxy server, so that the address information of the server proxy server corresponding to the server can be found in the address scheme table by using the address information of the server in the Http request.
Step S13: and sending the Http request to the server proxy server by using the address information of the server proxy server.
Specifically, after the address information of the server proxy server is found by the terminal proxy server, the Http request is sent to the server proxy server, wherein the terminal proxy server can select a free connection from a pre-established TLS connection pool to obtain a TLS connection connected with the server proxy server, the Http request is sent to the server proxy server by using the TLS connection, and the TLS is used for encrypting the connection and transmitting data, so that the security of the data in the transmission process is improved.
Step S14: and receiving an Http reply sent by the server proxy server.
It should be noted that, by means of the TLS connection pooling management, the multiplexing connection can be performed to the maximum extent possible, and the connection utilization efficiency is improved, so that the terminal proxy server can receive the Http reply sent by the server proxy server through the TLS connection, where the TLS connection between the terminal proxy server and the server proxy server is not changed, and the TLS connection multiplexing is still implemented by sending the Http request to the server proxy server for the terminal proxy server.
Step S15: the Http reply is sent to the terminal.
In the embodiment of the invention, the terminal proxy server can send the Http reply to the terminal through the TCP connection of the terminal by using the first mapping relation; the first mapping relation is a corresponding relation between a TLS connection and a TCP connection of a terminal, when the TLS connection connected with a server proxy server is established by a terminal proxy server, the first mapping relation is bound with the TLS connection by using a mark of the TCP connection between the terminal and the terminal proxy server, so that the first mapping relation is obtained, the TLS connection can be determined to correspond to the terminal by using the first mapping relation, the terminal proxy server can quickly send an Http reply to the terminal, and address information of the terminal is not required to be searched by using address information in the Http reply.
Therefore, the communication between the terminal and the server adopts the proxy server as the relay, so that the Http request sent by the terminal is sent to the terminal proxy server, the terminal proxy server sends the Http request to the server proxy server, receives the Http reply sent by the server proxy server, and finally forwards the Http reply to the terminal, thereby realizing the efficient and simple multi-data center access method.

Step S22: and sending the Http request to the server by utilizing the server address information in the Http request.
Specifically, the server proxy server may send the Http request to the server using a TCP connection.
Further, at this time, a corresponding relationship between the TLS connection and the TCP connection may be established, and the label of the TLS connection and the label of the TCP connection are bound, so as to obtain the second mapping relationship.
Step S23: and receiving an Http reply sent by the server.
Specifically, after the server processes the Http request, the server generates a Http response, and the server proxy receives the Http response generated by the server.
Step S24: and sending the Http reply to the terminal proxy server.
Specifically, the server proxy server may determine, by using the second mapping relationship, a TSL connection corresponding to a TCP connection used by the server, so as to send the Http response to the terminal server proxy corresponding to the server through the TLS connection; the second mapping relation is the corresponding relation between the TLS connection used by the terminal proxy server for sending the Http request and the TCP connection of the server.
