ApacheMobile Filter

The Goal
• Help people to detect easily any type of device
• have one solution for any platform (Unix, linux, OS X, Windows)
• give a simple solution for any programming language (PHP,
Python, JSP, Ruby, Perl etc....)
• Manage Images easily
• High performane

What is the Apache Mobile Filter Project ?
“Idel Fuschini has created Apache Mobile Filter
that allows you to access WURFL from any
programming language, not just Java and php that
is traditionally used for dynamic mobile web sites.
The module detects the mobile device and passes
the WURFL capabilities on to the other web
application as environment variables. It can also be
used to resize images on the ﬂy to adapt to the
screen size of the mobile device.”

Silvian Leuthold:
“After many years in mobile industry I can say that AMF is simply the
most straightforward approach I've seen for solving common mobile
internet challenges like device recognition, media delivery and mobile
web design. Thanks a lot to Idel who was always available for
support and consulting when needed. Great Job!. October 21, 2011”
Scott Pakin:
Given the mess the mobile Web is in, with devices ignoring handheld-
targeting stylesheets, lying about their screen resolution, and otherwise
impeding the development of portable Web sites, Apache Mobile Filter
really helps tame the complexity of delivering content that's suitably
formatted for the target device. November 02, 2011

Advanced Cache System
• Two architecture of caching:
• The Apache Mobile Filter when it has identified a mobile device, stores the
capabilities in a persistent cache (filesystem)
• The Apache Mobile Filter when it has identified a mobile device, stores the
capabilities using memcached (http://memcached.org). Ideal solutions in
cluster architectures.

Device Detection
ApacheMobile Filter

Device Detection overview
AMF suite from 3.40a version supports several device repositories, each Device Repository has a
dedicated module
• AMFLiteDetectionFilter: is suggested to use for solution that not need exaclty the type of device, but
only if the device is amobile or not. Is nor require a Device Repository
• AMF51DegreesFilter*: this module use 51Degrees (http://51degrees.mobi) as device Repository
• AMFDetectRightFilter*: this module use DetectRight (http://www.detectright.com) as device Repository
• AMFWURFLFilter*: this module use DetectRight (http://www.scentiamobile.com) as device Repository
*this module has advanced cache system on ﬁlesystem or using memcached

Remember:
This module is suggested to use only to use with AMFSwitch module, is not so precise how to use a Device Repository
At startuo the module verify on apachemobilefilter.org if there are new parameter to get, ig you want to disable this
option you can set:
PerlSetEnv AMFDownloadParamURL on true
In production is suggested to set the AMFProductionMode on true:
PerlSetEnv AMFProductionMode on true

If you need to add more capabilities or useragents that are not includes into the DeviceRepository add this papameter:
PerlSetEnv PersonalWurflFileName mydevicerepository.xml
The path is the AMF_Home. An example for your device repository file:
<wurfl_patch>
<devices>
<device user_agent="mickey mouse" fall_back="root" id="generic">
<group id="fb">
<capability name="mynewcapability" value="false"/>
</group>

AMF with Memcached
the advantage to use AMFWURFLFilterMemcached
This picture and the text are from http://memcached.org and can explain the advantage of this
architecture:
“memcached allows you to take memory from parts of your system where
you have more than you need and make it accessible to areas where you
have less than you need.
memcached also allows you to make better use of your memory. If you
consider the diagram to the right, you can see two deployment scenarios:
! 1.! Each node is completely independent (top).
! 2.! Each node can make use of memory from other nodes (bottom).
The first scenario illustrates the classic deployment strategy, however
you'll find that it's both wasteful in the sense that the total cache size is a
fraction of the actual capacity of your web farm, but also in the amount of
effort required to keep the cache consistent across all of those nodes.
With memcached, you can see that all of the servers are looking into
the same virtual pool of memory. This means that a given item is
always stored and always retrieved from the same location in your
entire web cluster.
Also, as the demand for your application grows to the point where you
need to have more servers, it generally also grows in terms of the data
that must be regularly accessed. A deployment strategy where these two
aspects of your system scale together just makes sense.
The illustration to the right only shows two web servers for simplicity, but
the property remains the same as the number increases. If you had fifty
web servers, you'd still have a usable cache size of 64MB in the first
example, but in the second, you'd have 3.2GB of usable cache.
Of course, you aren't required to use your web server's memory for
cache. Many memcached users have dedicated machines that are built to
only be memcached servers.”*

If you use proxy to access to the AMFwebservice, is suggested to use AMFWSCacheControl. With this

How can I retrieve the values of the capabilities of
wurfl?
Retrieve the WURFL capabilities value is very simple all the information are setting into the Apache Environment AMF_<uppercase wurfl capabilities name> for example:
To read the WURFL capabilities max_image_height you must read the environment value AMF_MAX_IMAGE_HEIGHT.
How to read environment in PHP ?
The php code is:
$_SERVER['AMF_MAX_IMAGE_HEIGHT'];
a test page in php is downloadable:
http://mobilefilter.cvs.sourceforge.net/viewvc/mobilefilter/ApacheMobileFilter/test_page/php/php_test.php?view=markup
How to read the value in JSP (for Tomcat)?
Before in the httpd.conf file where you have configure mod_jk you muse add this:
JkEnvVar AMF_MAX_IMAGE_HEIGHT undefined
The Java code is:
request.getAttribute("AMF_MAX_IMAGE_HEIGHT")
How to read the value in PERL?
print $ENV('AMF_MAX_IMAGE_HEIGHT');
ApacheMobile Filter

AMF and mod_rewrite
Now AMF is usable with mod_rewrite (http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html). The mod_rewrite can read the environment
variables that AMF passes.
The most important are:
AMF_DEVICE_IS_MOBILE, AMF_IS_TABLET
Here some example how to use it:
All mobile devices are redirect
In this example you can redirect only the mobile devices to the mobile site:
#Conﬁguration AMF Filter
#
PerlSetEnv AMFMobileHome /usr/local/AMF
PerlSetEnv ServerMemCached localhost:11211
PerlTransHandler +Apache2::AMF<your favorite module>Filter
# or
PerlTransHandler +Apache2::AMF<your favorite module>FilterMemcached
RewriteEngine on
RewriteCond %{ENV:AMF_DEVICE_IS_MOBILE} ^true
RewriteRule ^(.*)$ http://m.foo.org [R=301,L]
AMF<your favorite module>FilterMemcached is for AMFDetectRightFilter, AMF51DegreesFilter, AMFWURFLFilter and AMFLiteDetectionFilter
ApacheMobile Filter

AMF and mod_rewrite
All mobile devices are redirect except tablet
In this other example you permit to tablet to access the desktop version:
#
# or
RewriteEngine on
RewriteCond %{ENV:AMF_DEVICE_IS_TABLET} !^true
ApacheMobile Filter

AMF and mod_rewrite
Permit mobile devices to access to desktop
Sometime it’s possible to be able to mobile device to access on PC site, with AMF is simple you need to deﬁne the
FullBrowserMobileAccessKey like:
PerlSetEnv FullBrowserMobileAccessKey fullbrowser #the value you can change
and in your mobile page write this link:
<a href=”/?fullbrowser=true”>Desktop Version</a>
In httpd.conf the conditions are:
#
# or
RewriteEngine on
RewriteCond %{ENV:AMF_DEVICE_IS_TABLET} !^true
RewriteCond %{ENV:AMF_FORCE_TO_DESKTOP} !^true
