title: In what scenarios is recommended a reliable session?
body: <p>In few words, if I am not wrong, a session is used when I want to ensure that the packages are sent in order, and to be able to use sessions is needed a reliable connection.</p>
  
  <p>But my doubt what kind of applications need that? In my case is a simple application in which a client request to a service data from a database, the service get the data from the database and send to the client the results. Also the client can requeset to add, modify or delete data from database. In this case, should I need a reliable connection and sessions or not?</p>
  
  <p>Thanks.</p>
