Apache Mobile Filter

Intro to AMF

Every year more then 300 new devices

Device Fragmentation ProblemApacheMobile Filter

Each mobile device has many capabilities

screensize ?

imagetype ?

wifi ?

xhtml ?

screen resolution ?

navigation type ?

streaming type ?video streaming type ?

ajax ?

gif animated ?j2me ?os ?

gif animated ?

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.

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.

ApacheMobile Filter

Device Detection

ApacheMobile Filter

Device Detection overviewAMF 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

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> </device> <device id="apple_iphone_ver4_3"> <group id="fb"> <capability name="mynewcapability" value="true"/> </group> </device> </devices></wurfl_patch>

AMF with Memcachedthe 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.”*

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_rewriteNow 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/AMFPerlSetEnv AMFProductionMode truePerlSetEnv ServerMemCached localhost:11211

PerlTransHandler +Apache2::AMF<your favorite module>Filter# or PerlTransHandler +Apache2::AMF<your favorite module>FilterMemcachedRewriteEngine onRewriteCond %{ENV:AMF_DEVICE_IS_MOBILE} ^trueRewriteRule ^(.*)$ http://m.foo.org [R=301,L]

AMF<your favorite module>FilterMemcached is for AMFDetectRightFilter, AMF51DegreesFilter, AMFWURFLFilter and AMFLiteDetectionFilter

ApacheMobile Filter

AMF and mod_rewriteAll mobile devices are redirect except tablet

In this other example you permit to tablet to access the desktop version:

#Configuration AMF Filter#PerlSetEnv AMFMobileHome /usr/local/AMFPerlSetEnv AMFProductionMode truePerlSetEnv ServerMemCached localhost:11211

PerlTransHandler +Apache2::AMF<your favorite module>Filter# or PerlTransHandler +Apache2::AMF<your favorite module>FilterMemcached

RewriteEngine onRewriteCond %{ENV:AMF_DEVICE_IS_MOBILE} ^trueRewriteCond %{ENV:AMF_DEVICE_IS_TABLET} !^trueRewriteRule ^(.*)$ http://m.foo.org [R=301,L]


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:

#Configuration AMF Filter#PerlSetEnv AMFMobileHome /usr/local/AMFPerlSetEnv AMFProductionMode truePerlSetEnv ServerMemCached localhost:11211PerlTransHandler +Apache2::AMF<your favorite module>Filter# or PerlTransHandler +Apache2::AMF<your favorite module>FilterMemcached

RewriteEngine onRewriteCond %{ENV:AMF_DEVICE_IS_MOBILE} ^trueRewriteCond %{ENV:AMF_DEVICE_IS_TABLET} !^trueRewriteCond %{ENV:AMF_FORCE_TO_DESKTOP} !^trueRewriteRule ^(.*)$ http://m.foo.org [R=301,L]
