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. You are required to download and compile the
HAProxy source code including WURFL device detection: please refer to the HAProxy documentation for build 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
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:
global wurfl-data-file /usr/share/wurfl/wurfl-eval.xml wurfl-information-list wurfl_id model_name is_tablet #wurfl-information-list-separator | ## 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)]
Based on the configuration above, the
X-WURFL-All header value will result in something like
(all wurfl informations configured in wurfl-information-list, in the same order as listed, separated by a comma)
X-WURFL-Properties header value will result in something like
(only wurfl_id and is_tablet informations, in the same order as listed in
wurfl-get() call, separated by a comma)
wurfl-information-list configuration directive may include:
wurfl_idContains the device ID of the matched device.
wurfl_root_idContains the device root ID of the matched device
wurfl_isdevrootTells if the matched device is a root device. Possible values are "TRUE" or "FALSE"
wurfl_useragentThe original user agent coming with this particular web request
wurfl_api_versionContains a string representing the currently used Libwurfl API version
wurfl_infoA string containing information on the parsed wurfl.xml and its full path
wurfl_last_load_timeContains the UNIX timestamp of the last time WURFL has been loaded successfully.
wurfl_normalized_useragentThe normalized user agent.
wurfl_useragent_priorityThe user agent priority used by WURFL.
Capabilities and virtual capabilities
Refer to WURFL capabilities for all capabilities and virtual capabilities names.
