Unity WebGL call a .exe file on a server and get back data?

Hello there,

I'm currently working on a project that will be builded in webgl. It uses a asset that runs a .exe (cmd window) file to convert data that I need. But this does not work in webgl as it can't call the .exe file. So now I'm searching for solutions. I tried to changes pathes and everything but nothing worked. Now my thought would be to make a second unity project that runs on a server and waits for a request. When the request gets send out of the unity webgl project, the unity project on the server hears that request and runs the asset, after it is finished it will send back the gameobject created. But I haven't tested it yet. Would their be any other possible way?

Thanks in advanced!
