title: squid3 can't access google.com or bing.com
body: <p>I've a strange problem with squid3. It is normally working and I can access most web sites through the proxy. However some sites like</p>
  
  <pre><code>google.com
  bing.com 
  </code></pre>
  
  <p>just seem to get blocked but not always. Restarting squid3 doesn't seem to help or either clearing the /var/spool/squid3 ( cache ) directory.</p>
  
  <p>If I login to the machine that squid3 is running on and</p>
  
  <pre><code>wget --no-proxy google.com
  </code></pre>
  
  <p>then there is no problem however if I wget through the proxy it never responds. Most other websites are accessible including stackoverflow.com which I am using through the proxy right at this moment. Any idea what might be special about google.com and bing.com so that squid3 is treating them differently and is there any setting in the squid3 conf file that might be related to such behaviour.</p>
