Azure Redis Cache Connection String
Detects Azure Cache for Redis connection string patterns. This pattern is based on a Microsoft Purview built-in sensitive information type. Users already running Purview may prefer to enable the built-in SIT directly, or use this version as a starting point for customisation.

- Confidence justification
- High confidence: redis.cache.windows.net domain combined with password parameter provides strong structural constraint unique to Azure Redis. Added context gating and exclusion rules improve precision and reduce incidental matches.

Known false positives
- Azure Redis documentation with placeholder connection strings. Mitigation: Check for common placeholder values and documentation context.
- Development Redis Cache instances with non-production credentials. Mitigation: Flag for review regardless since connection strings reveal infrastructure details.
