After waiting a while for another programmer on another team to provide a web service that I needed to call from a client side web form, I received word that it was ready. I could not get it to work because CORS headings were not being set correctly. After contacting them and letting them know, I got an email update to the team letting everyone know that they were waiting on me. After explaining that CORS headings were not there, I just built a PHP page to proxy the request, results and set the headers correctly so I can move on. I will remove it when they get their side fixed... if they ever do.
