title: Send multiple POST requests a once
body: <p>I have an iOS app that is send a POST request to my server and then it runs a function and returns some data back to the app.</p>
  
  <p>My question is if my app has lets say 100 people using it at the same time and make the POST request in quick succession, is this going to case an error? </p>
  
  <p>I am on a shared server if that matters.</p>
