1) Depends upon browser
2) Usually re-submits the request
3) Check on Google
4) Try yourself to see various scenarios

When Submit a Form and while submit is working ,press the Refresh , that it will go same request and insert duplicate records,but i want validation of button.

In your case, if the request is inserting some data and you want to prevent duplicate insertion then implement the validate method in your action form and verify if the data is already present in the db.

Or better use Post/Redirect/Get Design pattern

I heard Tokens for applying to buttons.can you please explain Tokens.

hi Ranga,
preventing dublicate form submission you need to configure token interceptor. please read the insturctions in below url.

Hi Sir,
thanks for reply,but by Using tokens(isValidateToken()) method we can resolve that problem,but i want sample example.Please provide sample example.

Hope you could have taken the trouble to search "Duplicate Form Submissions" on Google.
