Prevent form resubmission in symfony?

Question

JavaScript

after submitting the form, the same page is loaded
if you press f5 - the browser will ask for confirmation of resubmitting the form and if you press "ok" then the form will be resubmitted
all that googled - do a 302 redirect to the same page
is there any other option?

Answer 1

In the form handler on the server, do a redirect

Answer 2

location ref is a normal method, a standard solution to this problem.
as an option - use Ajax, if after submitting it does not go to another logical page.
