The question is easy enough, the solutions seems not to be:
I have a Formhandler form with 3 Steps (the form is behind a login, so there is a logged in frontend user). When I use the browsers back / forward buttons I get cache errors like: - Cache miss in Chrome - Document expired in Firefox
I already tried to send different types of cache headers with no effect. Does anybody know if it is possible to solve this? Killing the browsers buttons in a multistep form is something that's going to annoy my users for sure.
Thank you for your help!
