Teman2,,
saya masih baru dalam ilmu proxy, saya mo tanya tentang konfigurasi proxy,, saya diminta menganalisa konfigurasi dari proxy yang menggunakan squid.
apa dari konfigurasi tersbut bisa diketahui
1. besar cache yang dipakai,
2. metode cache replacement nya, dan
3. metode dari proxy tersebut sepeti (round-robin atau parent sibling).

dibawah ini saya lampirkan contoh konfigurasi 1 server proxy (sebenarnya ada 4 server).

atas jawaban dan pencerahan nya saya ucapkan terima kasih..
