Answer 1

The answer depends on how many such requests will happen and how many concurrently in your web app ? Connection pooling is usually a better idea if you expect your web app to be busy with 100s or even 1000s of user concurrently logged in. If you are only doing this as a side project and expect less than few hundred users, you can probably get away without pooling.
