Thank you for using Squid v6 for this test.<br>
<br>
Unfortunately, due to Squid logging bugs, ERR_READ_ERROR/WITH_SERVER <br>
does not always mean what it says. For example, parent Squid could have <br>
closed the child-parent connection prematurely, but there could be other <br>
reasons. A full debugging log should give us more information.<br>

<br>
This is a child proxy response to the client. We need parent response to <br>
the child proxy. Look for "HTTP Server RESPONSE" lines instead.<br>
