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

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"
}

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"

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
