title: How to limit connections per second and IP on apache2?
body: <p>Hi! I have been having recurrent problems on my apache2, some group of people is bombarding my server with HTTP petitions to all my forms, everything collapses and my service is interrupted.</p>
  
  <p>How can I limit the amount of petitions per seconds to my users?
  Or which is the usual way to address this problem?</p>
  
  <p>Thanks!</p>
