we have a school list site and its developed under struts framework.
in my application, I have created school list and stored them into database. when I clicked on the back button (browser back), and once again the application is saving the same data. so its a bad approach. how can I prevent storing
the url after I saved : - http://localhost:9080/SchoolListBuilder/saveSchoolList.do and immediately the success view is showing correctly. when i click on the back button the warning page is displaying "Warning: Page has Expired" and i refresh that page, once again the data is storing with the same data into database.
what type of approach i need to follow to prevent double submission?
