Caching Youtube Using Squid Caching Proxy
I'm doing quick post today as I'm quite busy right now. But I don't want to make my friend Piju disappointed as he request me (quite so long... sorry heheh) about my changes on his previous squid.conf to cache youtube which is not working anymore since youtube make some changes on their video URL.
Here is my new /etc/squid/squid.conf

Since this happen for quite some time and I'm busy coding something else, I don't remember which part were changed. Maybe somewhere around url_regex. Perhaps if piju's blog are still running (which is currently not), we can do a diff to compare them. Anyway, here it is. These scripts are shared and distributed as is. If you change it, feel free to let me know. Otherwise, just enjoy!

the squid.conf and youtube dono how to use lah.
here's what i've done. i install a new ubuntu 10.10 and the user name is squid. computer name also squid. in a box with 160 Gig HDD.
sudo apt-get install squid will give me stable 2.7
Sudo nautilus to make the permission to for folders and to the sub folders of disk2-cache and disk1-1.
made the logs pid and another one using empty file.

Can you add some code for dailymotion video cache??
Thank You!
did you follow the same as he guided in the article?? i did not try this, but i wana to cache you tube videos ...
http://code.google.com/p/youtube-cache/
also i was working on a prototype using icap and not re-director or url store rewrite.
I merged your configuration and script with one from another site that also did not work and finally got something that appears to work.
Only I'm still not quite satisfied, as I am trying to get something that works with a proxy.pac file, so I can limit what I redirect to squid. Thus far this only works if I redirect everything.
