nyok...kita kompress image dilusca (Freebsd) via ziproxy....

Untuk mengenal ziproxy, silahkan melihat ke ziproxy website
Untuk keperluan ini diharapkan sudah menginstall squid/lusca di freebsd anda. Dalam hal ini ziproxy digunakan sebagai parent dari squid/lusca yang sudah dibuat.
Topologi yang saya pakai:

client ---> squid ---> ziproxy ---> INET.

dimana squid dan ziproxy berada dalam satu mesin/cpu.
Langsung ke TKP, dimana saya menginstall ziproxy via ports,

#cd /usr/ports/www/ziproxy
#make install clean

jangan lupa ditambahkan di /etc/rc.conf:

ziproxy_enable="YES"
ziproxy_config="/usr/local/etc/ziproxy/ziproxy.conf"

kemudian buat directory ziproxy di /var/log/ziproxy dan ubah kepemilikan kepada user dan group squid.

#mkdir /var/log/ziproxy
#chown -R squid:squid /var/log/ziproxy

selanjutnya diubah/diedit file /usr/local/etc/ziproxy/ziproxy.conf
yang diubah hanya bagian-bagian seperti dibawah ini, satu hal yang perlu diperhatikan bahwa yang dibawah ini hanya sebagian dari isi ziproxy.conf.

Port = 8081
Address = "127.0.0.1"
RunAsUser = "squid"
RunAsGroup = "squid"
ErrorLog = "/var/log/ziproxy/error.log"
AccessLog = "/var/log/ziproxy/access.log"
TransparentProxy = false
ConventionalProxy = true
AllowMethodCONNECT = false
UseContentLength = false
LosslessCompressCT = {
"text/*",
"application/asp",
"application/awk",
"application/cgi",
"application/class",
"application/css",
"application/dvi",

}
LosslessCompressCTAlsoXST = true
ProcessJPG = true
ProcessPNG = true
ProcessGIF = true

ProcessJP2 = false
ProcessToJP2 = true
ForceOutputNoJP2 = false
AnnounceJP2Capability = true
JP2ImageQuality = {50,50,50,50}

jangan lupa untuk menambahkan yang dibawah ini di squid.conf-nya:

cache_peer localhost parent 8081 0 no-query no-digest
never_direct allow all

sekarang silahkan di jalankan ziproxynya dan restart squid/lusca-nya.
menjalankan ziproxy:

#/usr/local/etc/rc.d/ziproxy onestart

merestart squid:

#squid -k reconfigure

selesai
