title: Apache HTTP server starts blocking requests after some time
body: <p>My hosting uses Apache server and I am connecting to the same url from the same client application which makes 10-20 requests per minute and after some time the server starts blocking the client app which shows errors for unreachable address and connection refused etc. 
  I am sure this isn't a connectivity issue as it is consistently reproducible.</p>
  
  <p>Any ideas how to setup the server so it won't block the client app's ip address? </p>
