title: Are secret URLs truly secure?
body: <p>I never leave backdoors in my system, but out of curiosity I was wondering if I left a secret URL like /x52d23r that allowed to bypass some sort of security, and this was only for my personal use---would that be somehow discovered by a third party without getting the information from me?</p>
  
  <p>For example, secret ports can be port scanned and fingerprinted, but can the same sort of tactic be done for secret URLs?</p>
