Distribution Server?

I want to run a tunnel connecting a server in my house to a web server. The web server will simply be a distribution server as it has more bandwidth to handle the request, but the local server in my house has the horse power to generate the files and handle the request.

Basically, I'd like the local server to generate and save the files to a folder on the web server.

Both systems are Windows Server 2012.

Is this even possible? Would it work to relieve my bandwidth issues?

Reverse proxy with the web server caching the files it receives from your local server.

Sounds complex.

What about a VPN tunnel? Have the local machine save the files to the Web Server?

Yeah, you would run the reverse proxy <-> local server connection over a VPN.

If you can pregenerate the files, why not do so and upload them all to the web server at once? If you can't, having a proxy query and cache the files from a backend server is the natural and right way.

I can pregenerate them, but several hundred of them update every hour.
