title: Why does Squid3 web proxy server block javascript files?
body: <p>Hi and thank you for reading my question.</p>
  
  <p>I have a fresh installation of squid3 proxy server (version 3.3.8) on ubuntu server 14.04 LTS.</p>
  
  <p>I am using squid just to filter some web sites so I am not using its caching capability.</p>
  
  <p>The problem is squid blocks js files (I can see them in chrome console blocked with Error message 503 Service Unreahable) so web pages are not loaded correctly.</p>
  
  <p>I am redirecting https and http traffic to squid tcp port 3128. But I am not filtering any web site.</p>
  
  <p>Is there anything I missed while configuring squid?</p>
  
  <p>Thank you for any help.</p>
