Caching results on a tab based web page

Dear All,

I have a web page which is having 4 tabs. The first tab is shown default on the load of the page. When the user clicks on the 2nd tab the data relevent to the second tab is retrieved from Database and displayed. The same happens when you move to 3rd and 4th tab for the first time.

If the user goes back to any tab which is already viewed by this user, I dont want to query it again from the Database. Instead we need to retrive the previous retrived results.

What is the best way to do it? Is there any caching mechanism to achive this.

Thanks n Regards

If the data is user-specific, cache it in the session. If it's common across all users, cache it in application scope.

This data is user specific. For this application there can be around 300-400 concurrent users. If we are putting it into session will it impact the performance of the web application?

Is there Caching API through which we can achive this more efficiently?

Please suggest.


Thanks

I'm sure there is -- I've always rolled by own.
