Steps	Solution Description
Step: 1	Make sure you have downloaded Apache 2.4.3
	Download From:
	#wget http://apache.techartifact.com/mirror//httpd/httpd-2.4.3.tar.bz2
Step: 2	Install the apache webserver: Extract the Zip file to the /data/downloads Directory
	#tar jxvf httpd-2.4.3.tar.bz2
Step: 3	Download apr check for the latest version

Step: 5	Extract the bzip files.
	#tar jxvf apr-1.4.6.tar.bz2
	#tar jxvf apr-util-1.5.1.tar.bz2
Step: 6	Rename to remove the version from the directory name.
	#mv apr-1.4.6 apr
	#mv apr-util-1.5.1 apr-util
Step: 7	Download pcre.  latest version and compile it
	#wget  ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.31.tar.bz2
	#./configure --prefix=/etc/httpd/pcre
	#make
	#make install
Step: 8	Install apache
	#./configure --prefix=/etc/httpd/apache2 --enable-mods-shared=all   --with-included-apr --with-pcre=/etc/httpd/pcre/
	#make
	#make install
Step: 9	Start Apache and verify installation
	# cd /etc/httpd/apache2/bin
	#./apachectl configtest
	# ./apachectl  start
	Or
	#cd /etc/init.d/httpd start
Step: 10	Apache Configuration file:
	#vi /etc/httpd.conf
	ServerRoot "/etc/httpd/apache2"
	Listen 80
	#Modules added for
	LoadModule expires_module modules/mod_expires.so
	LoadModule deflate_module modules/mod_deflate.so
	LoadModule headers_module modules/mod_headers.so
	LoadModule rewrite_module modules/mod_rewrite.so
	User apache
	Group apache
Step: 11	Install Dispatcher
	Get Dispatcher package: dispatcher-apache2.4-linux-x86-64-4.1.2.tgz
	#tar zxvf dispatcher-apache2.4-linux-x86-64-4.1.2.tgz
	#cp -r modules/* /etc/httpd/modules/
	Create a symbolic link to name 'mod_dispatcher.so' to the dispatcher module by running the command
	> ln -s dispatcher_apache_xxxx_yyyy.so mod_dispatcher.so
Step:12.1	Setting Dispatcher Handler
	SetHandler dispatcher-handler
	ModMimeUsePathInfo On
Options FollowSymLinks
AllowOverride None
Step: 13	Setting up the Publish renders 1,2,3 and 4
	#vi /usr/local/apache2/conf/extra/dispatcher.any
	/renders
	{
	/render0
	{
	/hostname "localhost1"
	/port "4503"
	}
	/render1
	{
	/hostname "localhost2"
	/port "4503"
	}
	/render2
	{
	/hostname "localhost3"
	/port "4503"
	}
	/render3
	{
	/hostname "localhost4"
	/port "4503"
	}
	}
Step: 13.1	Filter out specific URL from accessing over the internet
	/filter
	{
	# Deny everything first and then allow specific entries
	/0001 { /type "deny"  /glob "*" }
	#  /0001 { /type "allow"  /glob "*" }
	# Open consoles
	#     /0011 { /type "allow" /glob "* /admin/*"  }  # allow servlet engine admin
	#     /0012 { /type "allow" /glob "* /crx/*"    }  # allow content repository
	#     /0013 { /type "allow" /glob "* /system/*" }  # allow OSGi console
	# Deny query
	/0090 { /type "deny"  /glob "* *.query.json*" }
	/0091 { /type "allow" /glob "* /test/*" }
	/0092 { /type "allow" /glob "GET *.1.json*" }          # allow one-level json requests
	/0093 { /type "allow" /glob "* /auth/*" }
	}
Step: 13.2	# The cache section regulates what responses will be cached and where.
	/cache
	{
	# The docroot must be equal to the document root of the webserver. The
	/docroot "/data/aem/dispatcher/cache"
	# Sets the level upto which files named ".stat" will be created in the
	#/statfileslevel "0"
	# Flag indicating whether to cache responses to requests that contain
	# authorization information.
	#/allowAuthorized "1"
	# Flag indicating whether the dispatcher should serve stale content if
	# no remote server is available.
	/serveStaleOnError "0"
	# The rules section defines what responses should be cached based on
	/rules
	{
	/0000
	{
	# the glob pattern to be compared against the URL
	/glob "*"
	/type "allow"
	}
Step14	Cache invalidation for webserver and access to publishers
	/invalidate
	{
	/0002
	{
	/glob "/etc/segmentation.segment.js"
	/type "allow"
	}
	/0003
	{
	/glob "*/analytics.sitecatalyst.js"
	/type "allow"
	}
	/0004
	{
	/glob "*.js"
	/type "allow"
	}
	/0005
	{
	/glob "*.css"
	/type "allow"
	}
	}
Step: 15	Performance tuning
	# this configuration file extends the basic httpd.conf
	# it includes a number of options that are used to improve performance
	# turn off Etags completely, since they will differ across the cluster
	FileETag None
	# instead we use Expires and Cache-Control headers
	ExpiresActive On
	ExpiresByType text/css "access plus 1 year"
	ExpiresByType text/javascript "access plus 1 year"
	ExpiresByType image/gif "access plus 1 year"
	ExpiresByType image/jpg "access plus 1 year"
	ExpiresByType image/png "access plus 1 year"
	ExpiresByType application/x-shockwave-flash "access plus 1 year"
	# force set Vary header so it works with proxies and IE properly
	Header set Vary "Accept-Encoding"
	# enable compression for text file types: html, css, js, XML
	AddOutputFilterByType DEFLATE text/plain
	AddOutputFilterByType DEFLATE text/html
	AddOutputFilterByType DEFLATE text/xml
	AddOutputFilterByType DEFLATE text/css
	AddOutputFilterByType DEFLATE text/javascript
	AddOutputFilterByType DEFLATE application/xml
	AddOutputFilterByType DEFLATE application/xhtml+xml
	AddOutputFilterByType DEFLATE application/rss+xml
	AddOutputFilterByType DEFLATE application/javascript
	AddOutputFilterByType DEFLATE application/x-javascript
	DeflateCompressionLevel 9
	DeflateFilterNote Input instream
	DeflateFilterNote Output outstream
	DeflateFilterNote Ratio ratio
Step: 16	Test configuration
	# sudo /etc/init.d/httpd status
Step: 17	Stop Apache Server
	# sudo /etc/init.d/httpd stop
Step: 18	Start Apache Server
	# sudo /etc/init.d/httpd stop
Step:19	Log file location
	/etc/httpd/logs/
