Remote rendering of custom stl files

I was trying to perform a remote rendering using vtk.js client side and ParaViewWeb in server side. I was wondering if it is possible to send to the wslink Python server the stl files (or at least a path to them) that I want to show from the client side, at the moment I am just showing a default stl file that reads from the storage of the server machine. The scope is to keep the wslink server up and dynamically show different files without restart the server everytime I want to show display a new one. Is it possible?

Yes you can do what ever you need. You just need to architect your code accordingly.
WsLink give you rpc infrastructure for doing exactly that.

As a start, it might be even be easier to do it using trame.
