I am using SDL Web 8.1 and DXA 1.5 for my website development. I am facing an issue on the website. While traversing the website, if I click on the back button on the browser toolbar, the previous page's JSON Model is displayed in the browser. It is happening only on some pages, not all. However, if I disable the browser cache, it works fine.

I am also not able to debug it, as the request doesn't goes back to code. Can anyone please help? Has anyone faced a similar scenario before?browser developer control panel showing "Disable cache" enabled

It happens only on the product pages of our website, which are rendered as CMS Pages.

  • Looks like its caching issue, try to add "Vary: Accept" to the response header and try.

  • Can you edit your question and explain a few things in more detail? What exactly do you mean with rendered as CMS Pages? What browser are you using and could it be that it requests with an Accept: application/json header on the back button (see also stackoverflow.com/questions/16400639/…)? Aug 23, 2017 at 7:17
  • Hi Bart, it is happening on all browsers. Also, we were not appending any response header explicitly, so not sure why this happened for certain pages. However, after pushing "Vary: Accept" to response header, all seem to work fine. Aug 23, 2017 at 7:38

This is browser specific Cache issue, Add "Vary: Accept" to the response header and try to replicate your issue. I had resolved similar issue with above setting.

  • Thanks Raj, this seems to resolve the issue on my local environment. I will test it on server as well. Aug 23, 2017 at 7:20
