title: AWS CloudFront phppBB3 user-agent header
body: <p>I am experimenting setting up a site which includes phpBB3 to use AWS CloudFront. phpBB3 uses the user-agent header to detect robots and spiders so I have added a white list header to a CloudFront behaviour to forward the user-agent, this works but AWS warns against this because of the number of permutations of user-agent header.</p>
  
  <p>So, is there a better way of achieving the detection of robots in phpBB3 when using cloud front?</p>
