How to run blender on webserver?

I have a small script (model convertation), and this script works perfectly on local Win7 x64. I run it from command line

C:\SOFT\blender-2.79-windows64\blender.exe --debug-all --background --python

Script takes one file, then converts it to another format.
I want to run this script on webserver.
I mean, i want to put blender on webhosting, and execute script directly on webhosting.

  1. Which version of Blender i should use?
  2. What will be my syntax on hosting?
