This document is aimed at developers and system administrators who intend to install and configure the WURFL InFuze Module for HAProxy on Unix, Linux, and other Unix-based systems.
In order for the Module to work it is ESSENTIAL that the
libwurfl library is installed on your system.
libwurfl is provided in your Customer Vault/FileX.
WURFL device detection is included in the HAProxy source code from release 1.7-dev6 (http://www.haproxy.org/download/1.7/src/devel/). You are required to download and compile the HAProxy source code including WURFL device detection: please refer to the HAProxy documentation for building instructions. You will need the WURFL InFuze C API (libwurfl) installed on your system at compile time (refer to "installing libwurfl" above). To enable WURFL device detection, you will need to add USE_WURFL=1 to your HAProxy compile command as shown below:
$ make TARGET=<target> USE_WURFL=1
Optionally WURFL_DEBUG=1 can be set to increase logging verbosity.
The following are supported WURFL directives (see doc/configuration.txt in your HAProxy source tree):
Sample configuration file :
Sample configuration : global wurfl-data-file /usr/share/wurfl/wurfl-eval.xml wurfl-information-list wurfl_id model_name #wurfl-information-list-separator | wurfl-engine-mode performance #wurfl-engine-mode accuracy ## double LRU cache wurfl-cache-size 100000,30000 ## single LRU cache #wurfl-cache-size 100000 ## no cache #wurfl-cache-size 0 #wurfl-patch-file <paths to custom patch files> ... frontend bind *:8888 default_backend servers
There are two distinct methods available to transmit WURFL data downstream to the target application:
All data listed in wurfl-information-list
http-request set-header X-WURFL-All %[wurfl-get-all()]
A subset of data listed in wurfl-information-list
http-request set-header X-WURFL-Properties %[wurfl-get(wurfl_id,is_tablet)]
wurfl-information-list configuration directive may include :
Capabilities and virtual capabilities
Refer to WURFL capabilities for all capabilities and virtual capabilities names.
