The Reference session agent manages the detection and population of user agent information extracted from the request buffer. When a user submits a request to the web application, information about the visitor's browser, operating system, and type of application (mobile, desktop, BOT) is included in the request.
Note: This section describes a legacy mode for user agent parsing. Tealeaf strongly recommends using the newer version of user agent parsing.
By default, user agent parsing is enabled for new installs and upgrades. Legacy Mode must be enabled separately.
Legacy Mode enables the capabilities of the initial implementation of extended user agent parsing.
Note: With respect to Tealeaf users, the difference between the two implementation methods is seamless. However, the newer method provides superior matching capabilities, logging improvements, and better support for data anomalies.
Legacy Mode features include:
- Use of a self-pruning cache for quick access to the most frequently detected user agents. This cache is also used in the new implementation.
- Configuration files in use:
BrowsCap.csv- Public standard for fixed and bot user agents.UserCap.csv- User-defined configuration file of user agents not available inUserCap.csv.WURFL.csv- If the CX Mobile module is licensed, the WURFL standard must be downloaded and converted to CSV format, which contains the public WURFL standard for use by Tealeaf in identifying mobile user agents.
- Log messages sent to the Windows™ Event Log.
