The problem with my rails 5 app is that I have a link on a page that sends the user to example.com/PlaceHolderRoute. The route points to an action in the pages controller. The action is simply:
send_file('public/files/downloadable.pdf', type: 'application/pdf', disposition: 'inline')
I know that disposition: 'inline' will make the browser render the pdf, that is what I want and that's what it does. The issue is when the user uses the browsers back button. When the browser goes back to the page with the original button the pdf is still rendered on the screen & the page is not visible.
I've tried using a separate view for the action with an <object> tag for the pdf, but suffer the same problem. The page does become visible once it is manually refreshed. I've also tried using <meta> tags to prevent any caching to no avail. Something I also noticed is when the back button is used the URL in the browser does change and the server does respond as per usual. I think this a browser problem but I find that unlikely being this happens on every browser I've tried (Chrome, Firefox, Vivaldi, etc). Can anybody help me on this?
Edit:
This behaviour was not observed on Sinatra (still only using the same routes, html, & send_file)
