Amos thanks. I was sick over the weekend thus the late reply

Sorry by mistake I left out the mailing-list email on previously mail.
I would look into the donation link and see how I can tribute :).

Bug:) that was unexpected. I thought it was routine debugging work.

Here is output of squid -v

Squid Cache: Version 3.5.7-20150808-r13884
Service Name: squid
configure options:  '--bindir=/bin/squid' '--sbindir=/usr/sbin/squid'
'--sysconfdir=/etc/squid' '--datadir=/usr/share/squid'
'--libexecdir=/usr/lib/squid' '--disable-strict-error-checking'
'--with-logdir=/var/log/squid' '--with-swapdir=/var/cache/squid'
'--with-pidfile=/var/run/squid.pid' '--enable-ssl'
'--enable-delay-pools' '--enable-ssl-crtd' '--enable-icap-client'
'--enable-esi' '--disable-eui' '--localstatedir=/var/run/squid'
'--sharedstatedir=/var/run/squid' '--datarootdir=/usr/share/squid'
'--enable-auth-ntlm=fake' '--enable-auth-negotiate=kerberos,wrapper'
'--with-openssl' '--with-filedescriptors=65536'

The last output of http-headers was taken from cache.log itself.
