Is there a program to transfer files between servers over a local network without using a network drive?

Question

Programming

In general terms:
There is a web from which users send requests. Requests are stored in the folder from which another program is currently picking them up. This program cannot cope with the huge flow of requests and they stand in a queue. To avoid this queue, I see the solution only in direct transfer from one folder from the server to another server to a folder where a completely different program processes them.
Now about another server where requests are processed.
Client requests are devoured by the handler and laid out as a response to a folder from which these responses need to be transferred to another server, where they will be sent to the web server.
Briefly. From one folder to another between 2 servers, you need to transfer files via a local network without using a network drive.
Maybe someone knows the software for this?
