Amos,
Thank you for your reply.
I have version 3.5.12 compiled with Debian rules example provided here,
http://docs.diladele.com/administrator_guide_4_5/install/ubuntu14/tools.html
Do you think I could patch squid from 3.5.12 to 3.5.21 via patches
available at http://www.squid-cache.org/Versions/v3/3.5/
Or I could download tar.gz file and replace files from that folder to
Debian source folder ?
do i need any extra tools to build squid 3.5.21?
