checkout what is the latest version: ftp://ftp.cuhk.edu.hk/pub/packages/info-systems/www/squid/
probably this is more recent: https://github.com/squid-cache/squid
you could also try
git clone https://github.com/squid-cache/squid.git
and compile with the git source tree… let me know if it worked.

disk caching:
it seems like squid is doing RAM caching only per default.
to enable the disk caching … you go:
vim /etc/squid/squid.conf # Uncomment and adjust the following to add a disk cache directory. cache_dir ufs /var/cache/squid 1024 32 512 # 1024 = disk cache size in MBytes
Usage:
cache_dir ufs Directory-Name Mbytes L1 L2 [options]
‘Mbytes’ is the amount of disk space (MB) to use under this
directory. The default is 100 MB. Change this to suit your
configuration. Do NOT put the size of your disk drive here.
Instead, if you want Squid to use the entire disk drive,
subtract 20% and use that value.
‘L1’ is the number of first-level subdirectories which
will be created under the ‘Directory’. The default is 16.
‘L2’ is the number of second-level subdirectories which
will be created under each first-level directory. The default
is 256.
# how much RAM should be used for squid caching cache_mem 512 MB squid -k shutdown; # gracefully stop squid, waits 30 seconds for connections to close mkdir /var/cache/squid/00 mkdir /var/cache/squid/01 chown -R nobody:nobody /var/cache/squid/ squid -z; # recreate disk caching dirs? squid; # start squid again
it (should) create a structure like this:
ll /var/cache/squid/ total 196 drwxr-xr-x. 258 nobody nobody 8192 Aug 1 09:23 00 drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 01 drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 02 drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 03 drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 04 drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 05 drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 06 drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 07 drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 08 drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 09 drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 0A drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 0B drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 0C drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 0D drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 0E drwxr-x---. 258 nobody nobody 8192 Aug 1 09:23 0F -rw-r-----. 1 nobody nobody 648 Aug 1 09:24 swap.state du -a /var/cache/squid/ | sort -n -r | head -n 30; # find largest cache dir 2008 /var/cache/squid/ 1816 /var/cache/squid/00 1804 /var/cache/squid/00/00 364 /var/cache/squid/00/00/00000001 132 /var/cache/squid/00/00/00000020 108 /var/cache/squid/00/00/00000040 100 /var/cache/squid/00/00/00000000 76 /var/cache/squid/00/00/0000007A 76 /var/cache/squid/00/00/00000076 56 /var/cache/squid/00/00/00000050 56 /var/cache/squid/00/00/0000003F 52 /var/cache/squid/00/00/00000051 40 /var/cache/squid/00/00/00000011 36 /var/cache/squid/00/00/00000062 36 /var/cache/squid/00/00/0000004C 32 /var/cache/squid/00/00/00000043 32 /var/cache/squid/00/00/00000030 16 /var/cache/squid/00/00/0000004F 16 /var/cache/squid/00/00/0000004E 16 /var/cache/squid/00/00/00000037 16 /var/cache/squid/00/00/0000002C 16 /var/cache/squid/00/00/0000001A 12 /var/cache/squid/swap.state 12 /var/cache/squid/0F 12 /var/cache/squid/0E 12 /var/cache/squid/0D 12 /var/cache/squid/0C 12 /var/cache/squid/0B 12 /var/cache/squid/0A 12 /var/cache/squid/09

Reverse proxy?
if you want a reverse-proxy to accelerate web traffic by caching images and slow-generating pages, you might want to look at Varnish instead of Squid. It’s designed for reverse-proxy behavior, is lightning fast, and fairly simple to set up. Squid is designed as a forward proxy more than a reverse proxy. If you had a large social network site, you might want to consider using a CDN for the images and static content as well. Internet -> CDN -> Varnish -> Apache cluster You can also use Varnish as a load balancer as it can check node health.
