Monitor and debug HTTP calls from Adobe Reader

I installed Fiddler Web Debugger, and I am trying to configure it to monitor the HTTP calls from Adobe Reader/Acrobat DC. I have Dynamic PDF forms that will invoke URLs using JavaScript under Acrobat. I appreciate your guiding me to configure Fiddler to debug such HTTP calls. Mind you that I managed to debug the calls from IE, and now I want to debug the same from Adobe Acrobat DC.

Do not send the modified response to the browser cache?

is there a way to not store the modified file in response in the browser cache? When I modify the file it stays in the browser cache so when I open the browser without the fiddler and enter the page it continues with the modification. is there a way to prevent this file from going to the browser's cache? Thanks
