Systems and methods for handling client-server communications
View Patent ↗A computer-implemented method for handling client-server communications. The method may include 1) receiving, at a client system, a first command whose execution involves sending a first request to a server from a first transitory process associated with the first command; 2) initializing, on the client system, a communication proxy configured to relay communications between the server and transitory processes on the client system; 3) establishing a connection between the communication proxy and the server; 4) authenticating the communication proxy with the server; 5) establishing an inter-process communication channel configured to enable communication between the communication proxy and the transitory processes; 6) sending the first request from the first transitory process to the communication proxy over the inter-process communication channel; and 7) relaying the first request to the server via the connection between the communication proxy and the server. Various other methods, systems, and computer-readable media are also disclosed.

modification of the inter-process communication channel;
removal of the inter-process communication channel;
modification of the access control restriction.

reestablishing the connection between the communication proxy and the server;
stopping the communication proxy;
reinitializing the communication proxy;
closing the inter-process communication channel;
reestablishing the inter-process communication channel.
7. The computer-implemented method of claim 1 , further comprising:
receiving, at the communication proxy, a response to the first request from the server via the connection between the communication proxy and the server;
relaying the response to the first transitory process over the inter-process communication channel.
8. The computer-implemented method of claim 1 , further comprising closing the connection between the communication proxy and the server after a predefined time interval.
9. The computer-implemented method of claim 1 , wherein the first transitory process initializes the communication proxy.
10. The computer-implemented method of claim 1 , wherein the inter-process communication channel comprises at least one of:
a named pipe;
a memory-mapped file;
a Unix domain socket.
11. A system for handling client-server communications, the system comprising:
a communication proxy programmed to relay communications between a server and transitory processes on a client system;
an initialization module programmed to initialize, on the client system, the communication proxy;
a communication-channel-management module programmed to:
establish a connection between the communication proxy and the server;
authenticate the communication proxy with the server by sending credentials of a user to the server;
establish an inter-process communication channel configured to enable communication between the communication proxy and the transitory processes;
apply at least one access control restriction to the inter-process communication channel to prevent unauthorized access to the inter-process communication channel;
a request-identification module programmed to receive, at the client system, a first command whose execution involves sending a first request to the server from a first transitory process associated with the first command, wherein the first command is received from the user;
a request-dispatch module programmed to send the first request from the first transitory process to the communication proxy over the inter-process communication channel;
a communication-routing module programmed to relay the first request to the server via the connection between the communication proxy and the server;
