How to reuse rows data while using server side processing with pagination

I have been using the data tables component: server side processing with pagination. I am using a page size of 20 for a DB having thousands of records. As per my observation, every time i hit on a page-link, an AJAX request is made ti the server to fetch the rows data for that page index and page size.
Now i want to re-use the data which i already fetched for some particular page index, how do i do that?
