There is a link to page B on page A. Clicking the link can jump to page B. If I search for a piece of data on page A, search for the data and then click the link on page B (the data has nothing to do with page B). When entering page B If you then click the browser's return button to return to page A, an error will occur. If you do not search for data on page A and directly click the link to enter page B, and then click the browser's return button to return to page A, no error will occur. Why?

Is the search on page A a form submitted through POST?
