DevOps, CI/CD and Automation

I might be asking a dumb question...

here is my requirement-

1. I calling Ajax soap request to get xml data response - which is having CORS issue

2. I learnt we can make PHP curl call to avoid CORS issue

3. And do AJAX call to PHP script

my question, if I prepare Ajax sript, where do I place that file in JET application and how can I refer in Ajax call
