Need C | Java | PHP | Python | Perl | Node.js?

Server Side: Use code like...

Request.Browser["IsMobile"]

or

Request.Browser["IsTablet"]

... from within a web application server side to determine the requesting device type.

Client Side: Include...

https://[YOUR DOMAIN]/51Degrees.features.js?DeviceType&ScreenInchesDiagonal

... from Javascript to retrieve device type and physcial screen size information. Use Google Analytics custom dimensions to add this data for more granular analysis.

Offline: Use...

var detectionProvider = new Provider(StreamFactory.Create("[DATA FILE LOCATION]"));
var deviceType = detectionProvider.Match("[YOUR USERAGENT]")["DeviceType"];

... to perform offline analysis of web logs with User-Agent headers.

Recent Changes

Version 3.2.22 Highlights

  • Updated the Lite Binary files for December 2018.

Major Changes in Version 3.2

  • Embedded data has been removed from the assembly and now must be provided from the App_Data folder.
  • .NET 3.5 is not supported in this release in order to use memory mapped files and simplify overriding default browser capabilities.
  • In stream mode entity data properties that can allocate large arrays only initialise these arrays when needed.
  • Caches used with stream operation are now fixed memory size and serviced via the thread pool.
  • Automatic update processes uses temporary files rather than main memory to verify integrity of updated files prior to using them.
  • Temporary files are now created in the App_Data/51Degrees folder of the web application rather than a UNC path or the master data file folder.
  • Values associated with Profiles are now retrieved using a more efficient algorithm.
  • DataSet.Properties collection now has a string accesser to make retrieving properties by name simpler.
  • Web sites using memory mode use a byte array to improve start up time.
  • Version 3.2 data file formats are supported in parallel with version 3.1 data files.
  • 51Degrees unit tests are now part of the open source distribution.
