title: Squid, HTTPS pages intermitant and Windows 8 / IE11
body: <p>I have an odd issue, and have managed to replicate this problem at different locations with different installs of Squid.</p>
  
  <p>I will base my "problem" with my squid server at home.</p>
  
  <p>Running Fedora 20 (32bit), with Squid 3.3.11, firewall and iptables uninstalled/disabled.  The network is IPv4.  I have a couple of Windows 7 machines with IE11, and 1x Windows 8.1 machine with IE11.</p>
  
  <p>My problem is, on my Windows 8.1 machine with IPv6 protocols turned off, trying to load SSL based web pages (such as <a href="https://www.google.co.uk" rel="nofollow">https://www.google.co.uk</a> or <a href="https://www.facebook.com" rel="nofollow">https://www.facebook.com</a>), the initial page load results in an error.  Subsiquent loads either fail, part fail (IE main body of the site loads, but further SSL connections fail, such as image loads) or allow the page to load.).  Oddly enough though, I do not re-call having a problem with my banks website!  I would suggest that some websites seem to struggle more than others.</p>
  
  <p>A friend of mine also managed to replicate the fault on a squid server he setup with Windows 8.1.  He commented that using another browser such as Firefox, the problem is resolved so it seems limited to Windows 8.1, and IE11</p>
  
  <p>Using Wireshark, during the failed attempts, towards the end my machine sends back a load of TCP RST commands.</p>
  
  <p>However loading the same websites on my Windows 7 using IE11, or Windows XP with IE8, the problem does not appear, and until I moved to Windows 8.1, I had 0 problems with my Squid server.</p>
  
  <p>My Squid Config is fairly basic as I just use it for filtering adverts using a block list using SquidGuard, although an experiment ruled out SquidGuard as being the problem when I removed the relevant line from squid.conf.</p>
  
  <p>Thanks for reading and hope we can get to the bottom of this!</p>
  
  <p>Copy of my squid config. </p>
  
  <pre><code>#squid normally listens to port 3128
  http_port 3128
  
  #Allow local machine
  #acl manager proto cache_object
  acl localhost src 192.168.20.6
  
  # Only allow cachemgr access from localhost
  http_access allow manager localhost
  http_access deny manager
  
  http_access allow localhost
  
  # Define Local network
  acl localnet src 192.168.20.0/24
  http_access allow localnet
  
  #Redirect for SquidGuard
  redirect_program /usr/bin/squidGuard -c /etc/squid/squidGuard.conf
  
  # And finally deny all other access to this proxy
  http_access deny all
