The disclosed computer-implemented method for reducing network traffic by using delta transfers may include (1) receiving, from a client device, an original request message that requests at least one action from a server, (2) storing the original request message to serve as a foundation for a delta transfer that includes the original request message and at least one subsequent request message that builds upon the original request message, (3) receiving, from the client device, a subsequent request message that excludes at least a portion of the original request message to reduce redundancy between the original request message and the subsequent request message, and (4) applying the subsequent request message to the original request message to achieve the delta transfer while reducing the redundancy between the original request message and the subsequent request message. Various other methods, systems, and computer-readable media are also disclosed.
