What is the client of an application server when used with web server and web client?
When using ssh client and server in port forwarding, the programs involved communicate in a sequence:
application client <-> SSH client/server <-> SSH server/client <-> application server
When using web server and client with application server (note that here I am asking about concepts, so I guess that it is better to "separate" web server and application server, even if they are actually one program), I found an diagram from https://stackoverflow.com/a/24097629/156458.
Where is the application client?
Is it behind web client, like the case of using ssh client and server in port forwarding?
Or is there no other application client other than web server? Does a web server need to have the ability to work as a client to the application server?
Does that imply that a web server doesn't necessarily have the ability to work with any application server?
Thanks.

The client depends on where you look. The website visitor is the client to the webserver; the webserver is the client to the appserver; the appserver is the client to the DB server. Or, at a higher level, the website visitor is the client to the "server side system", if you consider the 3-tier design to be the "application service". You need to decide where, in the stack, you want to focus your attention. As it stands this question is all over the shop and needs serious reworking.
