BACK Button Issue

in my web app i used spring-mvc hibernate integration.
I used to save data in my student.jsp like "saveStudent.html"
In controller also get the request and save data's.then show success page.
but still url is "saveStudent"

If I press F5 or refresh then again record data's save.
after logout when i press back button then also show the previous data's.

please give me a simple solution friends because i have not more idea about spring web flow & spring security.
i heard about redirect & setCacheSeconds methods.are they good for my issue..?

If I'm not mistaken this is exactly what redirect is for. When you return a String from your submit method to forward to a success page, the user can still hit refresh or back and cause another submission (Browsers do tend to warn you about this). If instead you prepend "redirect:" onto your string, the browser will no longer resubmit the data on a refresh or hit of the back button.

So if your string was

Code:

---

return "success";

---

before, now it will need to read

Code:

---

return "redirect:success"

---

I believe. Hope that helps.
