CodeIgniter 3 with browser back button

Hello everyone ! I would like to know how to avoid "Document expired" from browser when back button is pressed with CodeIgniter. Thank you for your answers

We need a little more information than that, but normally it occurs with not handling form POST success or fails properly.

In fact I have a search engine which displays results according to the query entered in the input field. I can click on that result and see that result in a bit more detail. But now when I want to return to the other results of the query, I have a "Document Expired" and I have to reload the page. This is the behavior I want to prevent. the requests are of type post.
