How to avoid browser retaining the data entered? or is there a way to avoid caching?


Hello everyone,
I created a web form that I requires 2 XLSX files to be uploaded before you can submit the form, after submission of the form I have an action to refresh the page (A360 action).
The problem is that before the page was reloaded and a blank form was loaded but recently the page is loaded with the previous data.
1. Upload the files
2. Submit the form
3. Refresh the page

I'm thinking of adding a success redirect page to avoid this but I want to make sure first that there's no other way before proceeding as I have to delete my codes and redo some of it if that happens.
Thank you.
