Detailed Description

Configuration for building device detection data sets.

Introduction

Configuration structure extending fiftyoneDegreesConfigBase type with options specific to device detection. This adds configuration options around how a User-Agent is handled.

◆ FIFTYONE_DEGREES_CONFIG_DEVICE_DETECTION_DEFAULT_MAX_LENGTH

#define FIFTYONE_DEGREES_CONFIG_DEVICE_DETECTION_DEFAULT_MAX_LENGTH 500

Default limit in bytes for maxMatchedUserAgentLength.

No RFC or browser sets a limit on these headers. In the 20,000 evidence sample the longest pseudo header is 316 bytes and the longest User-Agent 331, with none over 500. A longer value is ignored, because in practice that does not happen.
