data extraction problem because session expired

While logging on to an application and pulling data in an injection detection that we have determined, after the session is terminated, it continues to pull

Let's say there are 10 tables in the database, we pulled 2 tables, while pulling the rest, the session ended and took an empty table, and when we renew the session, it pulled all the tables. The reason is that it continues to pull data when the session ends

thank you
