VBS scripting via Ruby web app — issues with multithreading



can someone please assist me with this problem https://stackoverflow.com/questions/55228872/vbs-scripting-via-ruby-web-app-issues-with-multithreading.

I’ve been trying to debug it for a while now and I can’t find the problem. I’m suspecting Rack, but can’t be sure.

If it would be easier, I can paste the entire content of SO post here.

Thank you.
