Squid with Cache Youtube

Puas rasanya, akhirnya bisa caching youtube (dan yang similar) :D.
Setelah sekian bulan “mangkrak” akhirnya jalan juga walau masih di mesin virtualbox.

Howto ini bukan untuk para pembenci youtube dan googlemap.
Tapi untuk youtube dan googlemap lovers.

bahan referensi yang jadi bacaan.

Versi yang saya pakai adalah squid-2.7.STABLE3, tidak tahu dukungan untuk versi yang lain.

  1. buat script untuk manipulasi youtube.
2.           #!/usr/bin/perl
3.           $|=1;
4.           while (<>) {
5.           @X = split;
6.           $url = $X[0];
7.           $url =~s@^http://(.*?)/get_video\?(.*)video_id=(.*?)&.*@squid://videos.youtube.INTERNAL/ID=$3@;
8.           $url =~s@^http://(.*?)/get_video\?(.*)video_id=(.*?)$@squid://videos.youtube.INTERNAL/ID=$3@;
9.           $url =~s@^http://(.*?)/videodownload\?(.*)docid=(.*?)$@squid://videos.google.INTERNAL/ID=$3@;
10.       $url =~s@^http://(.*?)/videodownload\?(.*)docid=(.*?)&.*@squid://videos.google.INTERNAL/ID=$3@;
print "$url\n"; }
  1. Lalu di squid.conf-nya edit seperti yang dibawah ini:
12.       acl store_rewrite_list url_regex ^http://(.*?)/get_video\?
13.       acl store_rewrite_list url_regex ^http://(.*?)/videodownload\?
14.       cache allow store_rewrite_list
15.        
16.       # Had to uncomment this again, because I couln'd login to google mail using IE6 (firefox had no trouble):
17.       acl QUERY urlpath_regex cgi-bin \?
18.       cache deny QUERY
19.        
20.       refresh_pattern ^http://(.*?)/get_video\? 10080 90% 999999 override-expire ignore-no-cache ignore-private
21.       refresh_pattern ^http://(.*?)/videodownload\? 10080 90% 999999 override-expire ignore-no-cache ignore-private
22.        
23.       storeurl_access allow store_rewrite_list
24.       storeurl_access deny all
25.        
storeurl_rewrite_program /usr/local/bin/store_url_rewrite

Hasilnya bisa dilihat di access-log, pada saat mengakses video yang sama, akan langsung hit.

# grep youtube access.log | grep TCP_HIT

Satu pesan dari Horacio Herrera Gonzalez, karena basic scriptnya tidak spesifik ke url tertentu, maka :

Warning! This code may match other sites not related to YT or GV.

He he he he, watching your bandwidth.

Karena beberapa user merasa kesulitan untuk mengaplied caching youtube.
