			= Notes =

			from [http://stackoverflow.com/questions/526832/why-does-http-localhost-redirect-to-my-default-virtual-host-once-i-setup-virtu stackoverflow.com] apache default vhost
			<pre>
			http://httpd.apache.org/docs/1.3/vhosts/name-based.html

			(Should be true for 2.x also)

			"If no matching virtual host is found, then the first listed virtual
			host that matches the IP address will be used.

			As a consequence, the first listed virtual host is the default virtual
			host. The DocumentRoot from the main server will never be used when an
			IP address matches the NameVirtualHost directive. If you would like to
			have a special configuration for requests that do not match any
			particular virtual host, simply put that configuration in a container
			and list it first in the configuration file."
			</pre>



			from http://wiki.apache.org/httpd/PerformanceScalingUp
			<pre>
			Requests for dynamically generated content usually take significantly
			more resources than requests for static content. Static content
			consists of simple filespages, images, etc.-on disk that are very
			efficiently served. Many operating systems also automatically cache
			the contents of frequently accessed files in memory.
			</pre>

			outro link interessante: http://wiki.apache.org/httpd/PerformanceScalingOut

			o que acredito:
			client pede uma página para o apache, o apache avalia o percurso
			(virtualhost), se o client usa cache o apache verifica a data do file,
			de qualquer jeito pega o file e entrega;
			o varnish recebe a requisição, gera um hasmap e verifica na cache
			dele, se tem na cache entrega, senão pede para o apache.

			Em caso de disponibilidade de memória, conteúdo muito requisitado tem
			muita probabilidade de já estar na cache RAM do OS, nesse caso uma
			leitura de um file resulta de uma leitura em um setor de memória já
			preenchido na leitura anterior; em caso não esteja na memória, o tempo
			de carregamento de file no disco deveria ser parecido. O apache
			poderia ter uma sobrecarga para coisas que faz amais do varnish
			(segurança, sessão, rewrite..)...

			Um pequeno ganho vezes muitas requisiçoes pode dar resultados, mas do
			monitoramento que temos não parece perceptível.



			para ver as portas abertas
			netstat -tulpn



			para ver o trafico em entrada, o comando a seguir da para entender:
			tcpdump -n -i eth0 host 187.126.64.20 and not tcp port 22 and not tcp port 80



			count dos processos do apache
			ps ax \| grep httpd \| wc -l

			* NOTE: define a global folder installation path

			for example, imagine

			<pre>
			/somewhere/
			\|-- site/
			\|-- app/ # as YOUR_APACHE_APP_DIR_OUTSIDE_APACHE
			\|-- www/ # as YOUR_APACHE_ROOT_DIR
			\|-- files/ # as YOUR_FOLDER_TO_HAVE_FILELIST
			</pre>

			so, the result will be

			<pre>
			/somewhere/
			\|-- site/
			\|-- app/
			\|-- apaxy-master/
			\|-- www/
			\|-- _dir_theme -> ../app/apaxy_master/apaxy/theme
			\|-- YOUR_FOLDER_TO_HAVE_FILELIST/.htaccess -> ../../app/apaxy_master/apaxy/htaccess.txt
			</pre>

			Installation:

			<pre>
			# global apaxy install, to be actived locally
			cd YOUR_APACHE_APP_DIR_OUTSIDE_APACHE
			wget https://github.com/AdamWhitcroft/Apaxy/archive/master.zip
			unzip master.zip
			rm master.zip
			mv apaxy-master/apaxy/theme/htaccess.txt apaxy-master/apaxy/theme/.htaccess
			mv apaxy-master/apaxy/htaccess.txt apaxy-master/apaxy/htaccess.txt_orig
			cat apaxy-master/apaxy/htaccess.txt_orig \| sed -e 's^theme^/_dir_theme^g' -e 's^//_dir_theme^/_dir_theme^g' > apaxy-master/apaxy/htaccess.txt
			rm apaxy-master/apaxy/htaccess.txt_orig
			cd YOUR_APACHE_ROOT_DIR
			ln -s YOUR_APACHE_APP_DIR_OUTSIDE_APACHE/apaxy-master/apaxy/theme _dir_theme
			# local apaxy activation
			cd YOUR_FOLDER_TO_HAVE_FILELIST
