What is applet to servlet communication?

Applet to servlet communication refers to the interaction between a Java Applet running in a client’s web browser and a Java servlet running on a server. This communication typically occurs over HTTP, where the Applet sends requests to the servlet to retrieve or send data, often using URL connections. The servlet processes these requests and returns responses, which the Applet can then use to update its UI or perform further actions. This interaction enables dynamic web applications by allowing client-side Applets to leverage server-side resources.
