BAD NEWS:

.
.

Some research update (Someone please confirm and post your comments)
YOUTUBE has split its videos into segments of 1.5 Mb each which is the approximation of the 51 seconds. I am sure YOUTUBE have taken this step to prevent people from caching entire videos. If you have a video which is 100 Mb large, it will be split into about 55-60 segments.
As of right now, storeurl.pl wont be able to cache it. Currently VIDEOCACHE plugin is

doing full cache of youtube but at higher 400 $ Per Year

Following is an update version of youtube caching

What is LUSCA/SQUID ?

LUSCA is an advance version or Fork of SQUID 2. The Lusca project aims to fix the shortcomings in the Squid-2. It also supports a variety of clustering protocols. By Using it, you can cache some dynamic contents that you previously can’t do with the squid.

For example
# Video Cachingi.e Youtube / tube etc . . .
# Windows / Linux Updates / Anti-virus , Anti-Malware i.e. Avira/ Avast / MBAM etc . . .
# Well known sites i.e. facebook / google / yahoo etch. etch.
# Download caching mp3′s/mpeg/avi etc . . .

Advantages of Youtube Caching !!!

In most part of the world, bandwidth is very expensive, therefore it is (in some scenarios) very useful to Cache Youtube videos or any other flash videos, so if one of user downloads video / flash file , why again the same user or other user can’t download the same file from the CACHE, why he sucking the internet pipe for same content again n again?
Peoples on same LAN ,sometimes watch similar videos. If I put some youtube video link on on FACEBOOK, TWITTER or likewise , and all my friend will watch that video and that particular video gets viewed many times in few hours. Usually the videos are shared over facebook or other social networking sites so the chances are high for multiple hits per popular videos for my lan users / friends.
This is the reason why I wrote this article. I have implemented Ubuntu with LUSCA/ Squid on it and its working great, but to achieve some results you need to have some TB of storage drives in your proxy machine.

Disadvantages of Youtube Caching !!!

The chances, that another user will watch the same video, is really slim. if I search for something specific on youtube, i get more then hundreds of search results for same video. What is the chance that another user will search for the same thing, and will click on the same link / result? Youtube hosts more than 10 million videos. Which is too much to cache anyway. You need lot of space to cache videos. Also accordingly you will be needing ultra modern fast hardware with tons of RAM to handle such kind of cache giant. anyhow Try it
We will divide this article in following Sections
1# Installing SQUID / LUSCA in UBUNTU
2# Setting up SQUID / LUSCA Configuration files
3# Performing some Tests, testing your Cache HIT
4# Using ZPH TOS to deliver cached contents to clients vai mikrotik at full LAN speed, Bypassing the User Queue for cached contents.

1# Installing SQUID / LUSCA in UBUNTU

I assume your ubuntu box have 2 interfaces configured, one for LAN and second for WAN. You have internet sharing already configured. Now moving on to LUSCA / SQUID installation.
Download LUSCA source and compile it using,

mkdir /temp

cd /temp

wget http://lusca-cache.googlecode.com/files/LUSCA_HEAD-r14809.tar.gz

tar xzvf LUSCA_HEAD-r14809.tar.gz

Update & Install some tools for ubuntu

sudo apt-get update

sudo apt-get install gcc build-essential sharutils ccze libzip-dev automake1.9

cd LUSCA_HEAD-r14809

Now compile LUSCA with following options

./configure
 '--prefix=/usr/local/squid' '--enable-removal-policies=heap,lru' 
'--disable-dependency-tracking' '--disable-arp-acl' 
'--disable-cache-digests' '--enable-cachemgr-hostname=localhost' 
'--disable-delay-pools' '--enable-epoll' 
'--enable-external-acl-helpers=ip_user' '--disable-ident-lookups' 
'--enable-linux-netfilter' '--disable-referer-log' 
'--enable-removal-policies=heap,lru' '--disable-snmp' '--disable-ssl' 
'--enable-storeio=aufs,null,coss' '--disable-useragent-log' 
'--disable-wccpv2' '--with-aio' '--with-maxfd=1048576' '--with-dl' 
'--with-pthreads' 'build_alias=i686-redhat-linux-gnu' 
'host_alias=i686-redhat-linux-gnu' 
'targe_alias=i686-redhat-linux-gnu''--enable-truncate' 
'--disable-unlinkd' '--with-large-files' '--disable-htcp'

sudo make all

sudo make install

All of Lusca/Squid configuration files can be found at
/usr/local/squid/etc/
and squid executable can be found at
/usr/local/squid/sbin/
Now We will edit squid.conf file to make it customize according to our requirements by . . .

nano /usr/local/squid/etc/squid.conf

Delete all previously lines , and paste the following lines.
Remember following squid.conf is not very neat and clean , you will find many un necessary junk entries in it, but as I didn’t had time to clean them all, so you may clean them as per your targets and goals.

Now create cache dir and logs files , and assign them necessary permissions.

mkdir /cache1

chown proxy:proxy /cache1

mkdir /var/log/squid

chmod 777 /var/log/squid

Now initialize cache dir by

/usr/local/squid/sbin/squid -z

SOTEURL.PL

Now We have to create an important file name storeurl.pl , which is very important and actually it does the
main job to pull video from cache.

mkdir /etc/squid

touch /etc/squid/storeurl.pl

chmod +x /etc/squid/storeurl.pl

nano /etc/squid/storeurl.pl

Now paste the following lines, then Save and exit.
